ZM 04:08 PM FPGA Development: RE: U-boot Error Message
Hi Jose,
I think your U-Boot environment may have become corrupted somehow: the "bad partition specification" error can occur when the partition number doesn't parse correctly. Since it _looks_ right in the error message, I suspect th...

Hi Evgeny,
Which branch of the kernel are you using? Mainline linux removed the keyword *spidev* from the compatible list of the spidev driver around the 4.x branches. The socfpga_mitysom5csx_leigh.dts uses an earlier kernel.
If yo...

Hi Jose,
I'm going to need a bit more info to help you get further. Can you provide your full console log? Also is the ubootenv you provided a copy and pasted from the uBootMMCEnv.txt file or is it the print out of running "print env"...

DV 09:29 PM PCB Development: RE: Bootup Peculiarities
Hi Lucas,
Sorry for the delay, the cyclone V can handle all the supplies powering up together.
Ah that could do it because as you said Bank7B is fixed at 1.8V and the PHY would be overvoltaging those IOs on the SOM. Sorry I didn't...

LU 09:15 PM PCB Development: RE: Bootup Peculiarities
On the dev board, R109 is a pullup for BOOTSEL2 from +1.8VIO, but there is also C523 and R503 connected to the bus and R503 is a pullup on the DVDDH_1V8 rail.
When I had to switch to the KSZ9021 because the KSZ9031 was unavailable, as...
