X310 Firmware (not FPGA Image) Load #698

Closed johnwstanford closed 10 months ago

johnwstanford commented 10 months ago

I'm trying to figure out how to update the firmware on the X310 and I can't find it documented anywhere. I'm not talking about the FPGA image. That process is well-documented. I'm talking about the code that runs on the ZPU:

https://github.com/EttusResearch/uhd/blob/master/firmware/usrp3/x300/x300_main.c

Is this stored in the EEPROM? Is there a way to access wherever it's stored over JTAG? Can you do a non-persistent load like you can do for the FPGA image? If you point me in the right direction to get started, I can figure out the details and I'm happy to update the documentation with whatever I find out. Thanks

John

The firmware is part of the FPGA bitstream. See here for details:

Thanks! That's exactly what I was looking for
