2 years ago okay... actually i'm having troubles just connecting. here's what i did:
cloned the repo: https://github.com/bouffalolab/bl_mcu_sdk
built openocd with following options:
./configure --enable-vsllink --with-sysroot
moved the resulting binary into the above cloned directory:
https://github.com/bouffalolab/bl_mcu_sdk/tree/master/tools/openocd
to replace it. because my flasher* is not supported by theirs.
but i get:
sudo ./openocd -f my_vsllink.cfg -f tgt_602.cfg

sorry to bother with a simple question :). I've successfully connected to the above board using openocd (via jtag):
and I have a *.bin file compiled...but im not sure how do I flash it from here, the openocd manual horrifies me like a novel. i'm strugglong to make anything out of it...how do I issue the flash command?
