U-boot prompt does not show in based-OMAPL137 Spectrum Digital EVM

Other Parts Discussed in Thread: OMAP-L137

Hi,

My R+D group is working with based-OMAPL137 EVM (Spectrum digital RevH). Because of some problems, we had to flash the board, using the "DaVinci Serial boot and  Flashing" software, allocated here http://sourceforge.net/projects/dvflashutils/files/OMAP-L137/v2.40/OMAP-L137_FlashAndBootUtils_2_40.tar.gz/download.

We are working in a Linux environment, so, following the instruction at the wiki page http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L137, open a terminal and write the next commands:

sudo mono ./sfh_OMAP-L137.exe -flash_dsp dsp-spi-ais.bin ubl-spi.bin u-boot.bin

The result is attached for seeing the details.. It seems EVM flashing is done ok. Previously, I could see the BOOTME prompt, selecting UART2 mode. Moreover, the three bootloaders have been copied from the PSP Release directory, so everything should perform. However, it is not true.

At the following step, when I change the micro-switches in order to select the SPIFLASH0 mode, power on the EVM and the u-boot prompt does not show in the terminal ( I am using minicom as a serial port and its configuration is ok). Instead of that prompt, I can see the next message:

Booting with TI UBL

Device OPP (300MHz, 1.2V)

After every reset of the EVM, I recieve the same messages... How can I restore the EVM and see the u-boot prompt again?? Before doing modifications at the EVM, I could run a NFS file system, changing environment variables of u-boot and so on.. What does EVM need?? Any suggestion or advise would be appreciated!

Thanks in advance

Óscar

    Hi Oscar,

    Which PSP release are you pulling your binaries from? I would recommend using the UBL and u-boot binaries found in the following PSP release.

    http://processors.wiki.ti.com/index.php/DaVinci_%28ARM9%29_PSP_Releases#AM17x.2FOMAP-L137.2FDA830

    Thanks,

    hi clinton,

    unfortunately, i get the same problem with a little difference. i need some help. thanks

    i am using OMAP-L37 EVM ASSY 511340 REV I. i need to update dsp-ais, arm-ubl, and u-boot from serial boot.

    my operate steps are:(follow the guide http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L137)

    1. download tool from http://sourceforge.net/projects/dvflashutils/files/OMAP-L137/v2.40/OMAP-L137_FlashAndBootUtils_2_40.tar.gz/download

    make sfh_OMAP-L137.exe

    2. copy dsp dsp-spi-ais.bin ubl-spi.bin u-boot.bin from evm cd or your url

    3.mono ./sfh_OMAP-L137.exe -flash_dsp dsp-spi-ais.bin ubl-spi.bin u-boot.bin

    turn boot switch to uart2 boot mode(10100), power on

    now, the host pc print the process of flash update. it seems flash success.(flash dsp-ais, flash arm-ubl, flash uboot, then print success)

    4. power down the EVM board, turn boot switch to spiflash boot mode(01010). then power on.

    the problem is:

    there is nothing printed from serial console.(i use kermit with 115200 Baud rate. it work well before with original EVM board )

    there is a difference with oscar. his board prints something, but my board prints nothing.

    i don't know if there is another PSP for my board to get the right files.

    thanks very much
