Elf upload error “fespi_write_reg() error writing 0x1 to 0x10014050”

I use a Digilent Arty A7-35T Artix-7 Xilinx FPGA with an Olimex ARM-USB-TINY-H JTAG debugger. The RISC V CPU core has been transmitted on the board, but an error occurred when I tried to upload the “hello” program elf which was found in freedom-e-sdk.

I followed this instruction and I was stuck at the last step.

The openocd tells me the error and the openocd.cfg file has been checked, I didn’t find anything suspicious.
