OMAP3530 bring-up (and installation of Angstrom)

OMAP3530 bring-up (and installation of Angstrom)

[Sergey Lapin]

Hi, all!

I have a new OMAP3530-based board which is totally empty.
omapzoom tools recognize ASIC ID on serial port, so I think it should
be possible
to bring it up this way. Do anybody have some minimal testing program
to flip some GPIO,
or character on serial?
I can't get any output from x-loader on either UART1 or UART3.. How
should I build binary for
it to be recognized by boot loader over serial?
No JTAG is here for this processor, and I have some troubles with
understanding of
Windows tools.

All the best,
S.

Does your board have any buttons or DIP-switches to select boot order? You may 
need to select the serial boot in order for the BootROM to send a handshake 
sequence on the UART3. The handshake on the therminal looks like several 
characters of garbage, starting with '40T'. The boot order is selected by a 
DIP-switch on OMAP3EVM and by a "User" button on BeagleBoard.

Then you need to use one of the available peripheral loaders to load a small 
version of U-boot over UART or USB into OMAP's SRAM and from there you can 
flash a final versions of x-load and U-boot into NAND. There are HOWTO's 
available, for example, here is one for BeagleBoard:
http://elinux.org/BeagleBoardRecovery

There should be a similar one for OMAP3EVM, but I currently cannot seem to 
find it...

I probably skipped some details on last email, sorry. I see ASIC ID
pattern (some garbage containing 40T).
I use pserial from omapzoom and try to upload self-built x-loader
binary, it reports success,
but I see no output on either of serial ports. No error messages,
nothing at all. That's why I'm interested in
minimal test program to use oscilloscope on some pins. I see that GPIO
configuration on OMAP3 is a lot
more complex than on AT91 and PXA, so I look for samples to check what
debugging could be inserted into
x-loader to look what happens. Also, a question remains - is it needed
for binary to be signed
befor uploading to serial, or not?

Thanks a lot,
S.

Yes, x-load/MLO need to be "signed". OMAP35x "signing" is just adding a 
header, see signGP tool:
http://beagleboard.googlecode.com/files/signGP.c

It's not that simple for OMAP34x, though...

Check the x-load build/sign procedures here:

Hi Sergey,

if you have a SDCard connector and can select it as a boot device using 
the BOOTx signals of the OMAP3530, just try to boot it this way.
I recently bring up a OMAP3530 board using the SDCard and beagleboard's 
x-load/u-boot & kernel as a basis with a few changes (8 bits NAND width 
in my case for example).
You can try directly with the BeagleBoard's binaries, it should give you 
some log :
