FS 12:14 AM Software Development: RE: MitySOM 5CSX SPI device not showing up in /dev: Hello Daniel,
I’m working with Evgeny on this and we’ve tried updating the compatible keyword to *cl,spidev* and we still don’t have SPI show up in /dev/, I have attached the updated dtsi file, also we are using kernel version 4.14.13... Franz Sattler

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... Zachary Miller

JB 05:21 PM FPGA Development: RE: U-boot Error Message: Hey Daniel,
Thanks for the help.
This is the full log:

I posted the UbootEnv.txt file. This is the print env output.

DV 03:17 AM Software Development: RE: MitySOM 5CSX SPI device not showing up in /dev: 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... Daniel Vincelette

EG 11:44 PM Software Development: MitySOM 5CSX SPI device not showing up in /dev: Hello --and hoping that someone can please help me with the following.
I’m trying to get the SPI device to show up in /dev. I added spidev for SPI0 to my dtsi file like in the socfpga_mitysom5csx_leigh.dts file from https://support.crit... Evgeny Galyaev

DV 08:30 PM FPGA Development: RE: U-boot Error Message: 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"... Daniel Vincelette

JB 09:27 PM FPGA Development: U-boot Error Message: Hello,
I am new to the HPS system and I was going through the guide for making U-boot and SD card provided after creating a design file in Quartus, but I always get the error message attached below. Have you encountered this error and c... Jose Berlioz

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... Daniel Vincelette
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... Lucas Uecker

LU 08:26 PM PCB Development: RE: Bootup Peculiarities: I've had the condition where the board will boot after HPS_POR_N is pulled low, and a condition where the boot doesn't occur but the illumination level of the LEDs on the module changes.
If I disconnect supply power to the ethernet (L... Lucas Uecker

LU 07:41 PM PCB Development: RE: Bootup Peculiarities: No lights come up on the module that lights up NCONFIG light.
On the second test module, both lights stay on until a few seconds after HPS_POR_N is pulled low. Then the yellow light goes off. This is the condition that got as far as t... Lucas Uecker
DV 07:34 PM PCB Development: RE: Bootup Peculiarities: Hi Lucas,
It is sounding like the SOM might of gotten damaged. Does the green LED on the SOM turn on? This is the power good LED that will turn on if all the power supplies on the SOM come up correctly.

LU 02:56 PM PCB Development: RE: Bootup Peculiarities: The Module that turned on our NCONFIG light did not boot on the dev board. I copied our NCONFIG LED from the dev board reference schematic with 3.3v -> 267 ohm resistor -> NCONFIG pin w/ TP10
HPS_POR_N is connected to a 1000pF cap and... Lucas Uecker
DV 02:48 PM PCB Development: RE: Bootup Peculiarities: Hi Lucas,
Did the SOM that was turning on the NCONFIG light on your baseboard boot fine in our Dev Kit?
What do you have connected to the HPS_NOR_N pin on your baseboard? Here's a snippet from our design guide about connecting up t... Daniel Vincelette
