Hello,
I built mcs E300ArtyDevKitFPGAChip.mcs file from https://github.com/sifive/freedom. I also made changes to openocd .cfg file according to instructions from Freedom E300 MCS file not working. However, although everything works fine with sifive_coreip_E31_FPGA_Evaluation_v2p0_0.mcs i still cannot upload and debug an application with E300ArtyDevKitFPGAChip.mcs.
I have to note that I am using JTAG debugger C232HM instead of recommended Olimex JTAG debugger, and it works fine with sifive_coreip_E31_FPGA_Evaluation_v2p0_0.mcs.
This is the output from the debug console:
