BlueMagic

BluePill/BlackMagicProbe support for CSR Programming

This is a fork of https://github.com/Frans-Willem/CsrUsbSpiDeviceRE

You can program the code onto a bluepill that has a bootloader or a black magic probe.

The pinouts are as follows:

BluePill/STM32 PIN	BlackMagicProbe	CSR-SPI
PA3	TDI	MOSI
PA4	TMS	CS
PA5	TCK	CLK
PA6	TDO	MISO

Note:

The Blue Pill can only talk at 3.3V. However the BMP should be capable of talking to a 1.8V target in the following manner: Prior to powering up the black magic probe, connect both SPI_EN and a targets 1.8V test point to the Black Magic's VCC. On power up, if the BMP sees that there is already voltage greater that 1V at VCC it will leave it's power supply off. In this manner, the 1.8V of the target is used to power the translator in the BMP and the communication happens at 1.8V.

Stuff to be careful of

• Make sure reset is hard pulled to 3v3
• Use "pscli.exe warm_reset @sleep_disable" to make sure sleep is disabled, execute right away then do psr stuff

Tweaking code? Compiling it yourself?

• Make sure you compile the libopencm3 libraries once before compiling the code yourself:

git submodule init;
git submodule update;
make -C libopencm3;

• keep 🤞
