Error: cpuConfigFile ../VexRiscv/cpu0.yaml not found

[BobMa0420]

Hi,I'm running VexRiscv on Sipeed TANG PRIMER 20K and I connect my board to the virtual machine via a usb jtag.

Then I'm trying to use openocd on my board with the command'src/openocd -c 'set VEXRISCV_YAML ../VexRiscv/cpu0.yaml' -f tcl/target/vexriscv_sim.cfg', the errors are as following.

Info : only one transport option; autoselect 'jtag'
Info : set servers polling period to 50ms
Error: cpuConfigFile ../VexRiscv/cpu0.yaml not found
Error: target 'fpga_spinal.cpu0' init failed

I'm wondering how cpu0.yaml is generated or what is the location of it. Looing forward to your rely!

Hi,
I'm not sure what configuration is exactly used, but in general cpu0.yaml look like :

debug: !!vexriscv.DebugReport {hardwareBreakpointCount: 0}
iBus: !!vexriscv.BusReport
  flushInstructions: [4111, 19, 19, 19]
  info: !!vexriscv.CacheReport {bytePerLine: 64, size: 4096}
  kind: cached

one way to get it, is to delete the VexRiscvLitexSmpCluster* files in pythondata-cpu-vexriscv-smp/pythondata_cpu_vexriscv_smp/verilog

Run the litex geneartion

then get the cpu0.yaml file in pythondata-cpu-vexriscv-smp/pythondata_cpu_vexriscv_smp/verilog/ext/VexRiscv
