Hello everyone. As a student at Tor Vergata University in Rome, I just bought some "mimas v2" cards, and we like this product very much. But now we are facing a problem that we can't solve: it's about the serial port. For our application, the serial port at 19200 bps was not enough and we needed to flash the firmware at 115200bps. But now we have a problem: just flashed the file bin the interface works in both directions but if we unplug and reconnect the board, the port only works in transmission (verified with the change of LEDs when we send special characters) But it does not work in reception. So if we flash the bin file on the board another time, the UART works in both directions. (In practice, every time we want to open a serial communication, we have to flash the bin file!) ps. If anyone is interested, the project is about the Xilinx SEM library (https://www.xilinx.com/support/documentation/ip_documentation/sem/v3_4/pg036_sem.pdf) regarding soft-error correction. (Soft errors are unintentional changes to the values stored in state elements caused by ionizing radiation). Then we will go to irradiate the FPGA (and the board as well) with a neutron beam, if anyone is interested, I can share (absolutely FREE, I love the open science! ♥) the schematics, project files, the results, and everything we have (maybe github?). pps. if u need, we can provide help in fixing pic firmware, if the problem is in it. Thanks in advance for the help.
