unrecognized JEDEC id bytes

i program the *.mcs to QSPI_flash  by xilinx Vitis 2020.2, it failed

the console information of Xilinx Vitis 2020.2  is:

-----------------------------------------------------------------------------------------------------------

U-Boot 2020.01-00107-g4a29a62 (Oct 13 2020 - 16:46:21 - 0600)

Zynq> ERROR: [Xicom 50-186] Error while detecting SPI flash device - unrecognized JEDEC id bytes: ef, 40, 20

Problem in running uboot

Flash programming initialization failed.

-----------------------------------------------------------------------------------------------------------

the QSPI Flash is W25Q512JVEIQ,  

if the QSPI Flash is W25Q256JVEIQ , it is success to program the mcs file.

i found:

    W25Q512JVEIQ   JEDEC id bytes is: EF, 40, 20

   WW5Q256JVEIQ JEDEC id bytes is : EF, 40, 19

How to solve the problem of program mcs file  failure by xilinx Vitis 2020.2

Hi @zhanghua_ds ,

Hope you are using Zynq device. May I know your QSPI flash part ? Is it supported device? Please make sure the qspi device is supported. Please refer to below answer record for more details.

Hi @zhanghua_ds ,

Please see UG908, page no.381 for Winbond flash part density. Xilinx supports Winbond with 128Mb flash density.
