I am bringing up a custom L138 board with a removable flash in SPI0. I've created a LED test app that I can successfully load and run using slh_OMAP-L138.exe. I've used AISgen to create a standalone image to boot from SPI0 and I have externally programmed this into the removable flash and it boots and runs as well.
I am now trying to use a customized sfh_OMAP-L138.exe to flash through SPI0 but can't get past "Waiting for SFT on the OMAP-L138...". I believe I've done the necessary modifications outlined in http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138 so I'd like some advice on debugging SFT. I've tried setting a LED at the start of DEVICE_init() but the LED is not responding so I feel SFT is not really running. It might help if someone could explain sfh process with detail on SFT loading and booting.
Here's my command line output of an attempt to erase:
sfh_OMAP-L138.exe -erase -p COM14 -targetType OMAPL138 -flashType SPI_MEM
