08:03 <Guest26> it is custom board as mentioned in my first messages

08:13 <trabucayre> Is it possible to see the schematic? Do you know a similar (lowcost) board with exactly the same FPGA (size+package)?

08:14 <trabucayre> It's always more easy to have a physical access to the FPGA to see why it's not working

12:08 <Guest26> I cant find the clock pin in the constraints file.

12:09 <Guest26> what is the pin used as clock?

12:10 <Guest26> I mean a clock for SPI

12:15 <trabucayre> with Xilinx devices this pin can't be driven directly

12:16 <trabucayre> This is done via STARTUPE2 primitive

12:18 <Guest26> aha, I know it is hard to know the issue without having the schematic. Unfortiniatly the board I'm worknig on it is not allowed to share its schematic. And I didnt find any custom board until now

12:18 <Guest26> any other*

12:26 <trabucayre> :-(

12:27 <trabucayre> I found one in trenz shop but 83euros without tax and shippment

12:27 <trabucayre> or 110euro via aliexpress

12:34 <Guest26> this is a schematic

12:55 <trabucayre> your Is your board is 3.3V (there is also a version 1.8v: https://www.trenz-electronic.de/en/FPGA-Module-with-AMD-Artix-7A50T-2I-16-MByte-Flash-1.8V-Config.-3-x-4-cm/TE0714-04-52I-8-A)

12:59 <trabucayre> 135e :-/ (+ 40e for the base board)

13:07 <Guest26> I will check which config my board is

13:14 <Guest26> IO voltage of the flash is 3.0

13:16 <Guest26> VCCO 0 is 3.3

13:17 <trabucayre> Ok so there is no specifics needs about bitstream
