[ECOS] Running redboot/ecos on OMAP5912 OSK

[ECOS] Running redboot/ecos on OMAP5912 OSK

[yasser Nour El-Din]

hi all,

I have an OMAP5912 OSK Version D board and i got a patch and OSK
related folders and i successfully build redboot with serial I/O
enabled.

I have now built redboot.bin and i tried to burn it on flash (using
flash utility program used to burn U-Boot) then  reset but it didn't
give any output on minicom terminal.

Does any thing must be changed in mlt_osk5912_rom.ldi.

If any body have working OSK source files to add to my ecos packages
please send it to me and  i will be very thankfull for him.

Thanks in advance
Yasser Nour

Hello Yasser,
I never tried loading the redboot with the flash utility program --
I've loaded onto OMAP5912 based boards using the built in serial
bootloader.  It's been ages since I used an OSK5912, but there should
be a DIP switch you can set to enable the on board bootloader.  I can
send you some Python scripts I use to load code on OMAP5912's, but if
you're not familiar with Python, it might be overwhelming.

If you have (and are familiar) with a TI emulator, what you can do is
to build an "SRAM" version of RedBoot -- this is a version that has
been designed to run from the 250kBytes of internal SRAM inside the
'5912.  Once that is running, you can use it to erase the flash,
format the flash, and download the ROM (flash) version of RedBoot.

Hello Yasser,
Please continue posting to the list so that everybody can benefit when
I say, "Sorry, I can't help you."  :-) Or, perhaps, K-C Lee will see
your post and offer some suggestions.

I never tried to get the ethernet working on the OSK, so I'm afraid I
can't help much here.  Perhaps the somebody else on the list has
gotten it working.  In lieu of that, I would suggest the judicious
application of calls to diag_print(), to see if the initialization
code for the ethernet driver is even being called, and, if it is, what
it is not finding to its liking.
