Is UART enabled on the standalone compute board? (not rtf drone)

My radio chip connects via the same pin layout as the telemetry port on the 80pin I/O connector through the UART protocol. Currently the port is getting voltage but my radio chip isn't powering on. I've also verified that the radio chip is functional. Does a custom firmware need to be flashed to the onboard FPGA to enable ports on the 80pin I/O connector? Does the aero compute github page provide such firmware?

Hello Plo3, Thank you for your interest in the Intel Aero Compute Board. The IO Expansion, where you connect the the 80-pin accessories connector communicates with the Altera MAX 10 FPGA from the board through a FPGA Connection. For a detailed view, you can check out page number 19 from Intel Aero Compute Board Guide https://www.intel.com/content/dam/support/us/en/documents/drones/development-drones/intel-aero-compu... Given the fact that your radio chip is not powering on, I would recommend checking once again the pinout for the Telemetry Port on the 80-pin accessories and make sure that the right PINs are used. You can find it on page number 14, 3.8.5 “J5” Telemetry from Intel Aero Compute Board Guide. If the connection is right and you still have this issue, please take a look at FPGA Sample Configuration - https://github.com/intel-aero/meta-intel-aero/wiki/95-(References)-FPGA#fpga-sample-configuration . The project contains implementations of several standard electrical interfaces. These include PWM, ADC, I2C, and UART. Please let us know the outcome! Thank you and best regards, Eliza

@ElizaD_Intel​ 

Hello,

 

I recently checked that the connector pins are used but the radio module is still not powering on. Regarding the github page you've linked, is the spi_xfer command all which is needed to enable the uart port when running on the default (aero-compute-board.jam) firmware?

Hello Plo3, Yes, those commands are used to set the baudrate, read and write the values on the UART port. Best regards, Eliza
