blue-pill-quickstart's Issues

README instructions may not produce a working OpenOCD setup

My *buntu setup already had a copy of OpenOCD installed in /usr/local, so following the instructions produced this error:

Open On-Chip Debugger 0.10.0+dev-00403-g3737dd69e738 (2018-04-20-22:55)

embedded:startup.tcl:60: Error: Can't find openocd.cfg

Error: Debug Adapter has to be specified, see "interface" command
embedded:startup.tcl:60: Error:

The solution was to run this instead:

openocd -f /usr/local/share/openocd/scripts/interface/stlink-v2.cfg -f /usr/local/share/openocd/scripts/target/stm32f1x.cfg

It might be a good idea to acknowledge that possibility.

tlink.x build error

I get the error below when trying run on ubuntu. I'm not familiar enough with rust yet but it looks like "-Tlink.x" is being used as a command line argument twice for rust-lld. Commenting out the rustflags line in .cargo/config fixes this for me.

Blue pills with clone CPUs

Hello and thank you!

It turns out that recent blue pills sometimes (always?) have a clone of the stm32 so the corresponding openocd config file needs to be updated as described here: https://www.eevblog.com/forum/beginners/unexpected-idcode-flashing-bluepill-clone/

In case that link breaks, the error printed by openocd is:

Info : using stlink api v2
Info : Target voltage: 3.140492
Warn : UNEXPECTED idcode: 0x2ba01477
Error: expected 1 of 1: 0x1ba01477
in procedure 'init' 
in procedure 'ocd_bouncer'

The fix is to update the ID in the stm config file to match the clone:

curl https://raw.githubusercontent.com/arduino/OpenOCD/master/tcl/target/stm32f1x.cfg > clone.cfg
sed -i 's/0x1ba01477/0x2ba01477/g' clone.cfg
openocd -f interface/stlink-v2.cfg -f clone.cfg

Can this be fixed by making a PR against openocd with the new config file? Would it be better to keep the config file for the one true original chip and document the possible modifications here? Perhaps this issue suffices to document this.
