[U-Boot] U-Boot: U-Boot 2010.06 doesn't boot from NAND Flash on AMCC Sequoia

[YURI ZHARIKOV]

Dear all:

We are Microelectronic Design and Applications (DMA) research group 
from University Carlos III of Madrid (Spain). At the moment, we are 
developing our own computational hardware platform, based on AMCC 
Sequoia board.

In the past, we used U-Boot 1.3.3 with AMCC Sequoia board, and PPC 
booted fine from NAND Flash. At the moment, with the same configuration 
of bootstrap (533MHz, NAND Boot, 33Mhz PCI) we are trying to use the 
last version of U-Boot (2010.06) on AMCC Sequoia board. But PPC doesn?t 
boot well, because there aren?t any information on HyperTerminal.

We use ELDK 4.2 for compiling U-Boot 2010.06 nand image on the same way 
that we did it for U-Boot 1.3.3:
$ export CROSS_COMPILE=ppc_4xxFP-
$ PATH=$PATH:/opt/eldk/usr/bin:/opt/eldk/bin
$ cd u-boot
$ make distclean
$ make sequoia_nand_config
$ make all

We boot PPC from NOR FLASH with previous version of U-Boot, and then we 
program NAND Flash memory with U-Boot 2010.06 nand image. We also use 
the same commands to do it that we used with U-Boot 1.3.3:
=> loadb 100000  /* transfer the U-Boot image */ => nand erase ENTER
=> nand write 100000 0 70000 ENTER

After that, we put J2 jumper and select SW2 (OFF-OFF-OFF-OFF).

Are we missing something?

Thanks and Regards,

I just tested the latest U-Boot version from the mainline git repository 
(master branch). NOR and NAND booting works just fine on Sequoia:

U-Boot 2010.06-00236-g7385c28 (Aug 02 2010 - 13:07:47)

CPU:   AMCC PowerPC 440EPx Rev. A at 495 MHz (PLB=165 OPB=82 EBC=55 PCI=41 
MHz)

       Bootstrap Option H - Boot ROM Location I2C (Addr 0x52), booting from 
NAND
       Internal PCI arbiter enabled, PCI async ext clock used
       32 kB I-Cache 32 kB D-Cache
Board: Sequoia - AMCC PPC440EPx Evaluation Board, Rev. F, PCI-Async=33 MHz
I2C:   ready

*** Warning - bad CRC, using default environment

PCI:   Bus Dev VenId DevId Class Int
USB:   Host(int phy) Device(ext phy)
DTT:   1 is 28 C
Net:   No ethernet found.


As you can see, I'm still using bootstrap option H (I2C EEPROM at 0x52). 
Easiest to do this is to use the "chip_config" command to reconfigure the 
bootstrap values for NAND (and/or NOR):

=> chip_config
Available configurations (I2C address 0x52):
333-133-nor      - NOR  CPU: 333 PLB: 133 OPB:  66 EBC:  66
333-166-nor      - NOR  CPU: 333 PLB: 166 OPB:  83 EBC:  55
333-166-nand     - NAND CPU: 333 PLB: 166 OPB:  83 EBC:  55
400-133-nor      - NOR  CPU: 400 PLB: 133 OPB:  66 EBC:  66
400-160-nor      - NOR  CPU: 400 PLB: 160 OPB:  80 EBC:  53
416-166-nor      - NOR  CPU: 416 PLB: 166 OPB:  83 EBC:  55
416-166-nand     - NAND CPU: 416 PLB: 166 OPB:  83 EBC:  55
500-166-nor      - NOR  CPU: 500 PLB: 166 OPB:  83 EBC:  55
500-166-nand     - NAND CPU: 500 PLB: 166 OPB:  83 EBC:  55 ***
533-133-nor      - NOR  CPU: 533 PLB: 133 OPB:  66 EBC:  66
667-133-nor      - NOR  CPU: 667 PLB: 133 OPB:  66 EBC:  66
667-166-nor      - NOR  CPU: 667 PLB: 166 OPB:  83 EBC:  55
667-166-nand     - NAND CPU: 667 PLB: 166 OPB:  83 EBC:  55


So you don't need to change the SW2 DIP switch. Only J2 is needed after 
boostrap EEPROM changes.

And here my environment commands for flashing the NAND U-Boot version:

=> printenv nload nupdate nupd
nload=tftp 200000 sequoia/u-boot-nand.bin
nupdate=nand erase 0 100000;nand write 200000 0 100000;setenv filesize;saveenv
nupd=run nload nupdate



Cheers,
Stefan

[U-Boot] U-Boot: U-Boot 2010.06 doesn't boot from NAND Flash on AMCC Sequoia

[YURI ZHARIKOV]

Dear Stefan:

Thank you for fast answer.

Our next problem consists in flashing the NAND without any U-Boot 
version, for our own developed system based on AMCC Sequoia board. The 
most important modifications in our board are:
- We removed from the original Sequoia design: NOR Flash, CPLD, USB 
ports and the second serial port. - We increased NAND FLASH size to 2Gb 
(NAND02GW3B2DN6E and MT29F2G08AADWP-ET:D TR in the next revision of our 
board).
- We decreased RAM size to 128MB.

Logically, we need that PPC boots from NAND Flash, and we use 
Lauterbach LA-7708 Debugger for program NAND. But now, without any 
previous U-Boot version, how can we apply the environment commands that 
you specify in your answer? Are there any configuration limitations 
that we must consider?

Thanks and Regards,
