I have the new rev D Arty Z7 board and can not write to QSPI flash the BOOT.bin file. I do not have this problem on the rev B Arty Z7 boards.
The error message is the following:
SF: unrecognized JEDEC id bytes: ef, 70, 18
Failed to initialize SPI flash at 0:0 (error -2)
Zynq> ERROR: [Xicom 50-186] Error while detecting SPI flash device - unrecognized JEDEC id bytes: ef, 70, 18
Problem in running uboot
Flash programming initialization failed.
I have already tried changing the board support package settings for the serial flash family and serial flash interface to the Windbond family but that did not help. What other changes should be made in the Xilinx SDK (baremetal) to generate a working BOOT.bin and succesfully write to flash.
Thanks a lot,
Stefan
