However it might be possible to do software update/ reprogramming of the target flash (DUT) wireless using the communication channels UART/SPI. Is my understanding correct? The idea is to fulfil atleast reprogramming of a sealed sensor-> Wifi->ESP-WROOM-32->SPI/UART-> SYNOPSYS BASED MICROCONTROLLER. If this could
