Other Parts Discussed in Thread: OMAPL138, OMAP-L138, OMAP-L137

Hi,

We have designed a custom board using c6748 processor .

Now we want to burn our code into SPI flash using UART2.

I search on internet for booting and flashing of c6748 but all the wiki pages will tell the procedure for OMAP l138.

There is a lot of data but which one procedure i can follow.

Kindly help me in this issue.

    Rana,

    C6748 and OMAPL138 share the same set of boot tools and utilities. All the wikis should have a section that describes the process for C6748 as well.

    Please refer to the OMAPL138 wikis and let us know if you find something missing.

    Regards,

    Rahul

    I too will soon be digging in the wikis for similiar information. The OMAP-L138 is ARM boot while the C6748 must be, and is, DSP boot. The OMAP-L138 ARMUBL instructions will make no sense on the C6748. I suspect that I have to partly refer to the OMAP-L137 (which is DSP boot) DSPUBL instructions. The TI Wiki is quite large and difficult to find information is one place. Is there wiki page that good place to start?

    Hi,

    I am using logic pd kit kit with omapl138 som.

    I use only dsp core of the Omap l138 processor.

    I made different projects and all are working fine when i debug with ccs.

    The main problem is the burn the code in SPI flash.

    I download the example from net for flashing that is OMAPL138-DSP-LED-v4 and the bin file in this example will work fine.

    I will load the bin file using this command in command line(sfh_OMAP-L138.exe -flash_noubl <binary application file>) and it will work fine.

    But when i make my .out file to .bin file and run this command sfh_OMAP-L138.exe -flash_noubl <binary application file> it will take more time and hangs the command line. the bar line whish shows data transfer on uart will transfered 100 % and after this command line hang.

    So kindly help me in this issue
