Dear experts,

My own serial flash is w25q64 combine with STM32G071RB nucleo board. I try to read the JEDEC ID (0x9F). Then, the module give me 0xEF0018. Based on the table you make, the JEDEC ID should be 0xEF4018. So, my memory type is 0x00. What should I do ? to make it 0xEF4018.

Thanks & Best Regards,

Dear experts,

Finally, I found the problem. The jumper cable is not connected with the board properly. Even it looks fine. I do a ring test with my multimeter to the jumper cable that connecting the module and the nucleo board and there are so much cable that are not connected properly. So, the solution is change that cables with proper one.

Thanks & Best Regards,
