It says SWD error here: My stm32 is as cold as the pcb next to it.
After last post, I did this:
Unplug the esp8266 from VCU
Connect st-link to swdprog on ISA FC VCU V2
Plug in st-link to PC
open st-link software
Select address 0x08000000
Open: https://github.com/jsphuebner/tumanako- ... loader.hex
Ctrl+P (target, program & verify)
Select address 0x08001000
Open: https://github.com/damienmaguire/Chadem ... hademo.hex
Ctrl+P (target, program & verify)
Ctrl+D (target, disconnect)
Unplug ONLY clock and data wire from VCU
Plug in the esp8266 to VCU
Plug back the st-link USB to PC. (Powering VCU from stlink 3.3v)
Connect phone/PC to esp8266 wifi
And now I have parameters! I don't know what went wrong the first round but then I was learning what do (so something went south) and now I just did what I wanted to do (and got lucky )
