Other Parts Discussed in Thread: UNIFLASH, , CC2538, CC3200, SEGGER
Hello all,
I have been using the USB-to-UART port to flash the QSPI FLASH on the IWR6843ISK board successfully using UNIFLASH. I wonder if I could bypass this step, and directly connect the CONN_RS232RX/TX ports of the IWR6843ISK radar module into external ports, and these to an FPGA with the metaimage (MSS+BSS) of the radar (noticce I have also access from the FPGA into the reset signaling, so I do not need to physically press the S2 I believe). Also, I noticed, that when I power the ISK board with the 5V connector, the board does not behave properly, whereas when powering it up with the USB connector, the radar was properly working.
So:
1.- Is it possible to connect the CONN_RS232RX/TX ports of the radar module to an external FPGA, and flash it from there using UART protocol (bypassing the USB-to-UART, UNIFLAHS), and
2.- Do you know if there is a known problem related to powering up the board with the 5V connection pins.
BR,
Gorka
