@Tim Edwards @jeffdi @Matt Venn I have a few MPW1 Chips with me and to test them I am trying out something different as I could not get hold of an FT232H Ic for USB to SPI. Following the caravel_pcb_v4_FTDI board I have connected the required 3.3v and1.8v LDO and 10 Mhz clock along with the reset button. Further I have connected an W25Q32 SPI flash to the QSPI Flash interface and am writing to the external flash memory using an Arduino. If my understanding is correct, on boot the Caravel will start reading from the flash memory and execute it in the management core. Currently my goal is to just get the management GPIO to blink an led and hence, I have used the /caravel_board/firmware/blink2/blink2.hex file. I just want to confirm : 1. If the steps that I have carried out make sense and is a feasible solution.
