Hi Team,

we are using CC3220S (Wi-Fi)  and CC2642R (BLE) and both are connected over SPI interface. In this case, CC3220S is master and CC2642R is  in slave mode.

Trying to flash CC2642R by CC3220S by using bootloader mode and for that one Boot mode pin using on CC2642R, also controlling Reset of BLE from CC3220S.

Please find below attached image for connection.

CC2642R is going in Bootloader mode and sending some packet in given bootloader packet format of CC2642R. we are getting acknowledge from CC2642R for ping command only not for others.

Are we missing something? Our idea is to flash firmware in BLE CC2642R via CC3220S. Please suggest.
