Pradeep;
Booting with a ramdisk is a matter of putting the appropriate image in the arch/ppc/boot/images directory (I obtained mine from the gsrd design files), adding the root=/dev/ram rw on the command-line boot options, making the .config changes for ram disk support and initrd usage, and issuing a make zImage.initrd command.
Beware when upgrading to 2.6.18.1 as you may have difficulties with the adapter.c you obtained previously. The adapter.c in EDK 8.2 is not as easy to find. Using the EDK to generate software components for linux will not expose the proper adapter.c. I had to use the path that Rick Moleres posted earlier to retrieve the adapter.c which I used for 2.6.18.1 and in my notes.

This is great! I played around for a while with the Sysace CF driver patches and got it to work. Since you are booting with ramdisk image would you be kind enough to add more text on how to do that? I see that you are using UART Lite? Does it require any special setting for the boot logs to show up on the standard hyperterminal.
I am planning on rebuilding the whole system using EDK 8.2 and linux kernel 2.6.18.1.

Below you will see the boot dump.
For those able to help, can
anyone provide insight as to the failure of setting PHY link speed?

I am booting with a ramdisk using initramfs. Aside from its being
somewhat harder to find documentation I beleive it is actually easier.
In the simplest form, create a directory on your host that contains
exactly what you want on the ramdisk.
Enable CONFIG_INITRAMFS
and point the CONFIG_INITRAMFS_SOURCE to that directory.
It is pretty much that simple. The linux build process creates a
kernel - I use zImage.elf that has the ramdisk compressed and concatentated.
Nothing except the Linux kernel itself has to make any accomidations
for the ramdisk. The bootloader does not have to deal with another file,
or pass pointers to it to Linux, ....
It took some time to get it working - mostly because I did nto know
what I was doing, but in hindsight it is really easy.

Hello,
I was able to get the booting with a ramdisk working and also David B./Peter's uartlite patches to work. Now I see the linux command line without any kernel panics. Thanks to everybody out there.
Next step is to get the PLB TEMAC 3.00.a working...
Question 1: I have started with the xapp902 reference design. I replaced the existing plb_temac_0 and hard_temac_0 instances with the plb_temac_0 (version 3.00.a) and hard_temac_0 (version 3.00.b). When I "generate libraries and BSP" I get the following error.
ERROR:MDT - intc () - Internal error: Number of interrupt inputs on opb_intc_0
(1) is not the same as length of total number of interrupt sources (2). If
any interrupt source is a vector then libgen does not support this use case
while executing
"error "Internal error: Number of interrupt inputs on $periph_name
($num_intr_inputs) is not the same as length of total number of interrupt.....
.....
ARG: C_PHY_TYPE VALUE: 1
ERROR:MDT - Error while running "generate" for processor ppc405_0...
Or is it better to generate the EDK design from start rather than using the reference design?
Question 2: For the adapter.c for TEMAC, I am using the C:\EDK\sw\ThirdParty\bsp\linux_2_6_v1_00_a\drivers\temac_linux_2_6_v2_00_b\src\adapter.c as indicated by Rick Moleres. Can I use it as is or it requires further tweaking? If yes, then what are the changes.
Question 3: Are the files under linux\arch\ppc\platforms\xilinx_ocp required? I thought the files in ../drivers/xilinx_edk => should take care of all the dma stuff?
Could someone provide some insight into all these questions?

Booting with a ramdisk is a matter of putting the appropriate image in the arch/ppc/boot/images directory (I obtained mine from the gsrd design files), adding the root=/dev/ram rw on the command-line boot options, making the .config changes for ram disk support and initrd usage, and issuing a make zImage.initrd command.
Beware when upgrading to 2.6.18.1 as you may have difficulties with the adapter.c you obtained previously. The adapter.c in EDK 8.2 is not as easy to find. Using the EDK to generate software components for linux will not expose the proper adapter.c. I had to use the path that Rick Moleres posted earlier to retrieve the adapter.c which I used for 2.6.18.1 and in my notes.

I am booting with a ramdisk using initramfs. Aside from its being somewhat harder to find documentation I beleive it is actually easier.
In the simplest form, create a directory on your host that contains exactly what you want on the ramdisk.
Enable CONFIG_INITRAMFS
and point the CONFIG_INITRAMFS_SOURCE to that directory.
It is pretty much that simple. The linux build process creates a kernel - I use zImage.elf that has the ramdisk compressed and concatentated.
Nothing except the Linux kernel itself has to make any accomidations for the ramdisk. The bootloader does not have to deal with another file, or pass pointers to it to Linux, ....
It took some time to get it working - mostly because I did nto know what I was doing, but in hindsight it is really easy.

This is great! I played around for a while with the Sysace CF driver patches and got it to work. Since you are booting with ramdisk image would you be kind enough to add more text on how to do that? I see that you are using UART Lite? Does it require any special setting for the boot logs to show up on the standard hyperterminal.
I am planning on rebuilding the whole system using EDK 8.2 and linux kernel 2.6.18.1.

For those interested, I have acheived some measure of success with the plb_temac driver.
I have attached a txt file of what I had to do to get it working under 2.6.18.1

Below you will see the boot dump.
For those able to help, can anyone provide insight as to the failure of setting PHY link speed?

i had problems getting the plb_temac driver to work at speeds higher
than 10 mbps until i modified the adapter.c
file to have the correct PHY address for my setup (i am using the
avnet V4FX12 mini-module board and the correct value was 4).
the phy address is usually determined by pullup/pulldowns on certain
pins on the gig phy chip.
this was under 2.4, but i looked at the adapter.c for the 2.6
xilinx_temac driver and it appears to just set this value to 0
look at line 2905 of adapter.c:
/* Assume the PHY to be at address 0x00 */
lp->gmii_addr = 0;
you should change that to reflect the address of your hardware setup.
hope this helps

Pradeep;
I found the process of "uprading" the xapp902 reference design to be troublesome when I removed the GMII loop-back; as
such, I aborted the process and just started from scratch.
I am currently debugging my design and have a functional plb_temac but only at 10Mbps speeds.

Subject: Re: minor progress with plb_temac v3.00a, EDK 8.2, & 2.6.18.1
Hello,
I was able to get the booting with a ramdisk working and also David B./Peter's uartlite patches to work. Now I see the linux command line without any kernel panics. Thanks to everybody out there.
Next step is to get the PLB TEMAC 3.00.a working...
Question 1: I have started with the xapp902 reference design. I replaced the existing plb_temac_0 and hard_temac_0 instances with the plb_temac_0 (version 3.00.a) and hard_temac_0 (version 3.00.b). When I "generate libraries and BSP" I get the following error.
ERROR:MDT - intc () - Internal error: Number of interrupt inputs on opb_intc_0
(1) is not the same as length of total number of interrupt sources (2). If
any interrupt source is a vector then libgen does not support this use case
while
executing
"error "Internal error: Number of interrupt inputs on $periph_name
($num_intr_inputs) is not the same as length of total number of interrupt.....
.....
ARG: C_PHY_TYPE VALUE: 1
ERROR:MDT - Error while running "generate" for processor ppc405_0...
Or is it better to generate the EDK design from start rather than using the reference design?
Question 2: For the adapter.c for TEMAC, I am using the C:\EDK\sw\ThirdParty\bsp\linux_2_6_v1_00_a\drivers\temac_linux_2_6_v2_00_b\src\adapter.c as indicated by Rick Moleres. Can I use it as is or it requires further tweaking? If yes, then what are the changes.
Question 3: Are the files under linux\arch\ppc\platforms\xilinx_ocp required? I thought the files in ../drivers/xilinx_edk => should take care of all the dma stuff?
Could someone provide
some insight into all these questions?

Booting with a ramdisk is a matter of putting the appropriate image in the arch/ppc/boot/images directory (I obtained mine from the gsrd design files), adding the root=/dev/ram rw on the command-line boot options, making the .config changes for ram disk support and initrd usage, and issuing a make zImage.initrd command.
Beware when upgrading to 2.6.18.1 as
you may have difficulties with the adapter.c you obtained previously. The adapter.c in EDK 8.2 is not as easy to find. Using the EDK to generate software components for linux will not expose the proper adapter.c. I had to use the path that Rick Moleres posted earlier to retrieve the adapter.c which I used for 2.6.18.1 and in my notes.

I am booting with a ramdisk using initramfs. Aside from its being somewhat harder to find documentation I beleive it is actually easier.
In the simplest form, create a directory on your host that contains exactly what you want on the ramdisk.
Enable CONFIG_INITRAMFS
and point the CONFIG_INITRAMFS_SOURCE to that directory.
It is pretty much that simple. The linux build process creates a kernel - I use zImage.elf that has the ramdisk compressed
and concatentated.
Nothing except the Linux kernel itself has to make any accomidations for the ramdisk. The bootloader does not have to deal with another file, or pass pointers to it to Linux, ....
It took some time to get it working - mostly because I did nto know what I was doing, but in hindsight it is really easy.

This is great! I played around for a while with the Sysace CF driver patches and got it to work. Since you are booting with ramdisk image would you be kind enough to add more text on how to do that? I see that you are using UART Lite? Does it require any special setting for the boot logs to show up on the standard hyperterminal.
I am planning on rebuilding the whole system using EDK 8.2 and linux kernel 2.6.18.1.

Below you will see the boot dump.
For those able to help, can anyone provide insight as to the failure of setting PHY link speed?

Robert,
I now created the BSP from scratch and its lot better than attempting to upgrade an existing design. I patched "xilinx_temac" and "xilinx_common" , but i am running into another error. I guess i have to start patching the code all over again.
Please take a look if you can comment on it...

I found the process of "uprading" the xapp902 reference design to be troublesome when I removed the GMII loop-back; as
such, I aborted the process and just started from scratch.
I am currently debugging my design and have a functional plb_temac but only at 10Mbps speeds.

For those interested, I have acheived some measure of success with the plb_temac driver.
I have attached a txt file of what I had to do to get it working under 2.6.18.1
I am using the plb_temac in DMA mode 3
Below you will see the boot dump.
For those able to help, can anyone provide insight as to the failure of setting PHY link speed?

steps for plb_temac drivers under EDK 8.2.02i (w/SP2.4+0)
Using plb_temac v3.00a & hard_temac v3.00b
Generate s/w libraries
1. copy or ftp the following files from C:\EDK\sw\ThirdParty\bsp\linux_2_6_v1_00_a\linux\
to the base directory of the linux source tree
USED:
arch\ppc\platforms\4xx\xparameters\xparameters.h
** UNUSED
arch\ppc\platforms\4xx\virtex.c
arch\ppc\boot\simple\embed_config.c
include\linux\xilinx_devices.h
2. copy C:\EDK\sw\ThirdParty\bsp\linux_2_6_v1_00_a\drivers\temac_linux_2_6_v2_00_b\src\adapter.c to
../drivers/net/xilinx_temac/adapter.c
3. copy or ftp ..\linux\arch\ppc\platforms\xilinx_ocp => drivers/xilinx_edk
Note: Remove all old files first *except* Kconfig, xio.h
4. modify drivers/xilinx_edk/Makefile with the following to look like this:
# Linux file to EXPORT_SYMBOL all of the Xilinx entries.
obj-$(CONFIG_XILINX_EDK) += xilinx_syms.o
#
# # The Xilinx OS independent code.
xilinx_syms-objs := xbasic_types.o \
xdmav3.o xdmav3_intr.o xdmav3_selftest.o xdmav3_simple.o xdmav3_sg.o \
xipif_v1_23_b.o \
xpacket_fifo_l_v2_00_a.o xpacket_fifo_v2_00_a.o \
xversion.o
5. Modify your copied xparameters_ml403.h (see notes below) as follows:
add these lines after #define XPAR_PLB_TEMAC_0_INCLUDE_RX_CSUM
#define XPAR_TEMAC_0_IPIF_RDFIFO_DEPTH XPAR_PLB_TEMAC_0_RXFIFO_DEPTH
#define XPAR_TEMAC_0_IPIF_WRFIFO_DEPTH XPAR_PLB_TEMAC_0_TXFIFO_DEPTH
#define XPAR_TEMAC_0_MAC_FIFO_DEPTH XPAR_PLB_TEMAC_0_MAC_FIFO_DEPTH
#define XPAR_TEMAC_0_TEMAC_DCR_HOST 0
#define XPAR_TEMAC_0_INCLUDE_DRE 1
6. (optional) modify arch/ppc/platforms/virtex.h to accomodate RX_CSUM XPAR
struct xtemac_platform_data {
#ifdef XPAR_TEMAC_0_INCLUDE_RX_CSUM
u8 tx_dre;
u8 rx_dre;
u8 tx_csum;
u8 rx_csum;
u8 phy_type;
#endif
u8 dma_mode;
u32 rx_pkt_fifo_depth;
u32 tx_pkt_fifo_depth;
u16 mac_fifo_depth;
u8 dcr_host;
u8 dre;
u8 mac_addr[6];
};
7. Modify ../drivers/net/xilinx_temac/adapter.c to remove #include <linux/xilinx_devices.h> and
add #include <linux/platform_device.h>
add #include <platforms/4xx/virtex.h>
____________________________________________________________________________________
NOTES:
1. Don't forget to copy EDK-generated xparameters.h to ../arch/ppc/platforms/4xx/xparameters/xparameters_ml403.h
