## openocd configuration setup in Eclipse or similar IDE
*Note: Make sure for each openocd instance use differenct port numbers for telnet/tcl/gdb*
## To manually read Flash info
*for example on ch32v003, run this from openocd bin dir*
`openocd.exe -f .\wch-riscv.cfg -c 'wch_riscv.cpu.0 configure -event reset-end {flash probe 0}' -c init -c reset -c exit`
