OMAP3 EVM Rev D (processor revB) - Reflash X-Loader and U-boot with flash 1.6 tool

Selso LIBERADO

Hi !

I did wanted to test dvsdk v4.01 on the EVM platform.

Infortunately I flash u-boot and it does not start on platform reset.

I tried to reflash it through flash utility v1.6.

Things get worst when by mustake I erase X-Loader.

Here are the steps I followed :

Fisrt I modified omapflash2nd.txt for nand recognition : CUSTOM_OMAP35XX_BOARD 343007 57 => CUSTOM_OMAP35XX_BOARD 343007 54

Then I modified configuration_evm35xx_micron_512m.txt because its nand address was 0x28000000, and conforming to hardware user guide the nand was at 0x20000000.

I recomplied X-Loader and signed it to get the ift file.

Now I launch the flash utility with config=OMAP35x, ECC Style=HWECC, file = x-load.bin.ift.

At startup the XLoader does not boot .

Worst If I relaunch the flash tool just to erase the x-loader region I get stuck in the middle of the process :

¯ -stdout

¯ -omap 3

¯ -no_force_package_alignment

¯ -com 1

¯ -t 60

¯ -p EVM_MDDR_MICRON_512M

¯ -2

¯ chip_erase NANDINFO1BITBOOT 00080000

¯ Leaving parameter file:temp_script.txt

¯ @temp_script.txt

¯ Looking for device (omap com1)

¯ Please turn off device, then turn it on again

¯ Awaiting ASIC id

¯ AsicId items 04

¯ AsicId id 01 05 01 34 30 07 54

What can I do know ?

Are my parameters correct ?

Hi Selso,

Could you check the behaviour of the system with pre-built images?

You can read in the following document how to copy boot loaders to NAND flash and check whether you use the same steps:

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/exports/TMS320DM3730_Software_Developers_Guide.pdf

If there isn't problem with pre-built images you can read a simple tutorial about how to build initial NAND x-loader.

Hi !

I did use also a pre-built image in vain.

I finally manage to get things working here is the howto :

1) SW4 is configured to boot on UART3

2) Modifiy targets OMAP35xx config file nand addr : 0x28000000 -> 0x20000000 (conforming to hardware user guide). Modify omapflash2nd.txt for ASIC ID compatibility : OMAP35XX_BOARD 343007 57 => OMAP35XX_BOARD 343007 54.

3) for x-load flash : ECC Style = HWECC, check ONFI Compliant Nand. for u-boot ECC Style=SWECC, check ONFI also.

3) lanch flash and boot card. It is flashed. Now switch serial cable on UART1/2 and reboot the platform. That's it.
