Hello

I am new to Openrisc.

I am trying to load mor1k in to de0_nano and boot that with the precompiled vmlinux-de0_nano.I am using openocd to load it using telnet connection.

When I try using the below command

halt; load_image /path-to/vmlinux-de0_nano; reset

CRC ERROR! match bit after write is 0 (computed CRC 0x2b7d8fa9)
CRC ERROR! match bit after write is 0 (computed CRC 0x2b7d8fa9)
CRC ERROR! match bit after write is 0 (computed CRC 0x2b7d8fa9)

What could probably go wrong?
Any help is appreciated.

Hi there,

Which instructions are you following? Can you share the link?

Hi

Thanks for the reply.

1. first I downloaded fuseSoc from github
2. Then build for de0 Nano
$ fusesoc build de0_nano
3. Then loaded .sof generated using quartus_pgm
$ quartus_pgm --mode=jtag -o p\;de0_nano_0.sof
4. Then downloaded openocd
$ ./bootstrap
$ ./configure --enable-ftdi --enable-usb_blaster_libftdi --enable-maintainer-mode
$ make
$ make install
5. $sudo ./src/openocd -s ./tcl -f ./tcl/interface/altera-usb-blaster.cfg -f
./tcl/board/or1k_generic.cfg

6. In another terminal
$ telnet localhost 4444

OpenOCD started
> halt; load_image /pathto/vmlinux-de0_nano; reset

CRC ERROR! match bit after write is 0 (computed CRC 0x2b7d8fa9)
CRC ERROR! match bit after write is 0 (computed CRC 0x2b7d8fa9)
