Program boot and application on SPI flash in a custom board

Other Parts Discussed in Thread: OMAP-L138

Hi all,

I've developed a custom board with TMSC6746 DSP. I have an SPI flash on CS0 of SPI1. I use UART0 to communicate between PC and DSP.

I'd like to use sfh_OMAP-L138 utility to flash boot and application on the SPI flash, but it doesn't work.

The utility locks after writing the message "Waiting for SFT on the OMAP-L138..."

Do I need to recompile the utility? On the development board usually the UART2 is used, while I'm using UART0.

My memory is mapped on SPI1 instead of SPI0... can this be a problem?

Any suggestion will be very appreciated.

Regards,

Paolo

    Hi,

    If it is a custom board, sfh utility needs modification.

    According to your custom board's SPI, DDR and UART changes, do the modifications in the source code of SFH and re-compile it and use it. For more info please visit below.

    Please let us know how it goes. Revert if you stuck inbetween.

    Regards,

    Hi Shankari,

    thank you for the info.

    Following the guide to rebuild the flashing utility, I see that I have to install the ARM compiler tools.

    Unfortunately Codesourcery G++ Lite is non more available. The link provided

    www.codesourcery.com/.../subscription3057

    is redirected to www.mentor.com/.../overview

    Do you know if there is still a place where I can download the latest free version of G++ Lite?

    Thank you for your support.

    Regards,
    Paolo
