Hi Jorge,
[quote user="Jorge Fernandez"]I would like to know if there is anything in common with the firmware dm814x_hdvpss.xem3 loaded once the linux kernel is loaded using the script /etc/init.d/load-hd-firmware.sh?[/quote]
I think both firmwares are using the VPDMA module that is inside the HDVPSS subsystem.
[quote user="Jorge Fernandez"]I would like to know is it possible to do all the firmware loading stuff in uboot[/quote]
I think this is possible, but not easy to implement. You can try putting a stripped version of XEM3 image into one of the partitions in the flash and then u-boot will be able to load the image into RAM. Then, the ELF loader (added to U-boot) is taking over from there and is reading all of the sections out of the ELF image and putting them where they go for the Cortex-M3 to use, as expected. Then U-boot could continue booting linux, as usual, from that point in time.
