@ -8,10 +8,29 @@ Only if you have a Stlinkv2 with STM32F103C8 versus the STM32F103CB on V2/1
|
|||
and you want to rewire and use the UART, consider reflashing the the Stlink
|
||||
firmware.
|
||||
|
||||
On StlinkV2, the original ST Bootloader can also be used with
|
||||
|
||||
- Compile firmware with "make PROBE_HOST=stlink ST_BOOTLOADER=1"
|
||||
|
||||
- Upload firmware with stlink-tool from [stlink-tool](https://github.com/jeanthom/stlink-tool.git).
|
||||
Before upload, replug the stlink to enter the bootloader.
|
||||
|
||||
- After each stlink replug, use call "stlink-tool" without arguments
|
||||
to enter BMP
|
||||
|
||||
Drawback: After each USB replug, DFU needs to be left explicit!
|
||||
On Linux, add someting like :
|
||||
|
||||
`> cat /etc/udev/rules.d/98-stlink.rules`
|
||||
|
||||
`SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="3748", ACTION=="add", RUN+="<path-to>/stlink-tool"`
|
||||
|
||||
for automatic switch to BMP on replug. However this defeats reflashing further
|
||||
BMP reflash as long as this rule is active.

## Wiring on Discovery and Nucleo Boards

|

If there is a 6-pin connector, connect an external target after removing
|
||||
the 2 jumper shortening the 4-pin connector like this:
|
||||
|
||||
1: VCC sense, used only for measurement
|
||||
|
||||
2: SWCLK
|
||||
|
||||
3: GND
|
||||
|
||||
4: SWDIO
|
||||
|
||||
5: nSRST (pulled high by on board target. Will reset with on board target
|
||||
unpowered.
