Hi,
The software driver supports SPI Flashes with the following parameters:
1. Address Width - 24 bit addressing
2. Data Rate is specific to the IoT chip:
CYW2070x supports SPI data rate upto 12MHz
3. Supports JEDEC's CFI (Common Flash Interface) compatible SPI Flash chips from Cypress Semiconductors, SST, STMicroelectronics, Atmel, MXIC, Adesto, Winbond.
Could you please clarify at what stage the download failed? Did you probe the SFLASH lines and confirmed whether the flash writes are failing?
- Can you put the device in recovery mode and try downloading?
Thanks & Regards,
Anjana

we put the device in recovery mode and reset,it still download failed. when changeed to MXIC Flash MX25R4035FZUIL0,the board download succesfully.
2. we'll let end customer to test SST,ST,Atmel, Adesto, Winbond flash samples with CYW20706, did need to modify what configuration in WICED SDK for supporting these flashs ?thanks.
