Continuing my adventure with VC-01 module (powered by Unisound US516P6) I found the OpenOCD used with JTAG programmer (VC_Burner B228) and fixed the configuration to get it working (WIP).

First we need to clone this specific openocd repository:

$ git clone https://github.com/andestech/nds-openocd

Then compile it (I enabled all the programmers supported by OpenOCD, but you just need aice)

$ ./bootstrap
$ ./configure --enable-internal-jimtcl --enable-maintainer-mode --disable-werror --disable-shared --enable-stlink --enable-aice --enable-jlink --enable-rlink --enable-vslink --enable-ti-icdi --enable-remote-bitbang --enable-usb-blaster --enable-presto --enable-osbdm
$ sudo make install

You need this OpenOCD config file:

$ cat openocd_nds32.cfg 
log_output iceman_debug0.log
debug_level 3
gdb_port 9902
telnet_port 9901
tcl_port 6666
source [find interface/nds32-aice.cfg]
source [find board/nds32_xc5.cfg]

gdb_target_description enable
gdb_report_data_abort enable
nds log_file_size 10485760
nds global_stop off
nds reset_halt_as_init on
nds boot_time 5000
nds reset_time 1000

Note: you need to edit /usr/local/share/openocd/scripts/interface/nds32-aice.cfg and use:

adapter_khz 12000

instead of 24000!


$ sudo openocd -f openocd_nds32.cfg -d3
