  1. As a part of my university project, I need to port an RTOS on the Nexys A7 50T and write a program involving the peripherals of the board. I'm thinking of using PlatformIO in order to program the FPGA as it's easy to understand for a beginner such as myself. But I'm having a lot of trouble finding the source files for the board having all the JTAG and the debugging modules. Such source files were available for Nexys A7 100T(https://university.imgtec.com/resources/download/rvfpga-1-1/) which I used for my internship. I can share these files if you want to. I need source files which consist of a bitstream file or through which I can generate a bitstream file and after which I could directly upload it on the board and program using PlatformIO. Could you help me with this or put me in contact with anyone who could help me ?
  2. I’m trying to debug a program Factorial.c on the Nexys A7 50T FPGA board using PlatformIO. I have procured its bitstream file from the GitHub repository. Shown below is the platformio.ini code: [env:swervolf_nexys] platform = chipsalliance board = swervolf_nexys framework = wd-riscv-sdk monitor_speed = 115200 board_build.bitstream_file = D:\STUDIES\NexysFiles\Nexys-A7-50T-OOB-2018.2-1\vivado_proj\Nexys-A7-50T-OOB.runs\impl_1\nexys50t.bit Shown below is the program code: #if defined(D_NEXYS_A7) #include <bsp_printf.h> #include <bsp_mem_map.h> #include <bsp_version.h> #else PRE_COMPILED_MSG("no platform was defined") #endif #include <psp_api.h> #define N 7 int main(void) { int fact = 1; int temp = N; while(temp > 0){ fact *= temp; temp -= 1; } uartInit(); // Initialize UART printfNexys("Factorial of %d: %d ", N, fact); } Using PlatformIO, the bitstream is uploaded successfully on the board: After clicking on “Run Debug”, the compilation is also done successfully: But the debug console fails with the following errors: My current driver used is: I have installed it using Zadig and have also tried reinstalling the driver but the same issue persists. Please help me resolve this issue.
