I'm doing some work on FPGA side under Linux Yocto on Terasic DE1-SoC board,
and frequently check the changes (IP on Avalon-ST) by re-program fpga But if I shall do this with blaster JTAG, the framebuffer (VGA) will be ruined, so Im converting sof to rbf, write it to flash, reinsert it to socket, etc, and reboot. But I guess there are should exist more easiest ways to do this ? For example load sof file with JTAG and just reload/modeprobe fb of Linux sys tools ? I tried to search out how to do it on standard (stripped ver) of Yocto on DE1 boards, but have not meet any convenient way except to build a new image of Linux ... Regards.
