Have anybody QSPI loader algorythm for Keil?

I can't create workable code....

12 REPLIES 12

I changed pins to my board and changed 4-byte mode to 3-byte mode.

QSPI initialising, memory_mapped_mode starts, but all readung bytes are "0x88"....

Same settings in main project works good....

0x88 is indicative of the flash part not being in QUAD mode, or command being wrong (unsupported, inconsistent with current mode, etc)

Would recommend doing a JEDEC READ ID, of one then both chips together (interleaved)

Thanks! Everything works! There was an error in the GPIO settings - I changed the numbers and ports, but did not change the parameters (AF9,AF10).
