Hello

We are trying to connect Adesto AT25SF641-MHB-T which is not supported by Wiced.

We can send JEDEC ID (9Fh) command and sometimes get the response from flash memory.

Since It isn't stable, we want to try to change the access timing.

How can we change the timing like SCK clock speed ?

Regards

I am assuming you have already done the necessary modification required in 43xxx_Wi-Fi/WICED/platform/MCU/BCM4390x/peripherals/spi_flash directory. If you have done that, you can look into the waf.sflash_write app and the .tcl script. A good point of debugging the issue will be enabling #define DEBUG_PRINT macro which should give you some idea about the responses.
