Writing Kernel to NOR Flash ?

Other Parts Discussed in Thread: AM1808, OMAP-L138, OMAPL138

I have been testing NOR Flash boot mode using AM1808 EVM. (LogicPD)

I write pre-builded arm-nor-ais.bin and u-boot.bin to NOR flash of UI board using norflash_writer

And I tired following command to flash NOR the uImage.

Download uImage and copy it to the NOR partition:

U-Boot> tftp 0xc0700000 uImage
U-Boot> protect off 60080000 +200000
U-Boot> erase 60080000 +200000
U-Boot> cp.b c0700000 60080000 200000

http://processors.wiki.ti.com/index.php/Booting_Linux_kernel_using_U-Boot#NOR_Flash

But uboot don't support 'protect' command.

The uboot I worte print the below message.

Booting with TI UBL
Device OPP (300MHz, 1.2V)

U-Boot 2009.11 (Mar 23 2011 - 13:13:04)

What is the version that supports 'protect' command?

This is an error in the documentation. The "protect" command is not necessary, as the NOR is unlocked by default.

Thank you your relpy.

likewise, 'erase' command is not supported in uboot.

I am trying to do the same thing (program u-boot and kernel into NOS Flash on the AM1808evm board).

Did this question ever get answered or did you switch to a different processor?

I am new to embedded LINUX so I'm sure to be missing something.

Actually the erase and protect command are supported. By default U-boot is built to support SPI Flash, so you will have to recompile for NOR flash support. Instructions are here:

http://processors.wiki.ti.com/index.php/GSG:_Building_Software_Components_for_OMAP-L1#Rebuilding_U-Boot

Once you change the #define to NOR_FLASH both commands are available.

I have already built u-boot with the NOR Flash support (Emil Lenchak told me how) but how does one program it into the NOR Flash

when the only u-boot in the target doesn't support NOR Flash and the XDS100v2 emulator doesn't work?

For now, Emil has succeeded in putting an updated u-boot in my NOR Flash (my XDS100v2 emulator still doesn't work, we used his XDS510) but it seems the AM1808EVM

development kit is not as useful as it is advertised to be.

Mellissa,

If you don't have a working emulator, then you can use the serial flasher and write the UBL and U-Boot to the NOR flash.

I tried that too (didn't work), but only last Friday did I find out that you cannot access the NOR Flash with the SD card pushed in.

I hope to get a chance to try it all again with the SD card pulled out.

I tried doing this again this time with the SD card pulled out and it failed. That is, the working u-boot image that Emil Lenchak programmed into the NOR Flash using his laptop and his XDS510 eumlator has now been obliterated by this action so now I'm no longer booting from NOR Flash.

Here I have copied the console session that claimed to be successful but in reality was NOT successful.

I finally succeeded in writing to NOR Flash by myself using:

sfh_OMAP-L138.exe -p COM8 -flash -flashType NOR -v arm-nor-ais.bin u-boot-nor.bin

The two things that made the difference are:

(1) doing this with the SD card OUT!!

(2) using the AIS file "arm-nor-sia.bin" made for me by Emil Lenchak.

I still need to know how to make a proper AIS file for myself.

I have played with AISgen for D800K006 to some length and have yet to be successful with that.

You don't need a custom AIS UBL, you can use the one that comes with the PSP. The source code is also there if you want to make modifications.

Also the newest revisions of the EVM have a hardware fix for the NOR/SDMMC issue, but in your case you must remove the card in order to boot from NOR.
