CMSIS-SVD for STM32WB

It is tedious job to find all the registers in the data sheets. There is CubeMX to create code for STM's MCUs, but mecrisp use pure assembler. There is convenient way to create equates for the assembler.

Install the STM32CubeIDE

and get the STM32WBxx_CM4.svd from the folder:

Line: 43 to 76

common/svd2forth-v3> make mem

Flash mecrisp to the Target

Nucleo Board

Connect Nucleo's ST-LINK USB to you PC. Erase the flash e.g. by openOCD, we use 768 KiB -> 192 sectors.

$ telnet localhost 4444
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Open On-Chip Debugger
> reset init

> flash erase_sector 0 0 192
erased sectors 0 through 192 on flash bank 0 in 4.583453s
> flash write_image mecrisp-stellaris-stm32wb55.hex

> shutdown
shutdown command invoked
Connection closed by foreign host.

USB Dongle

The USB Dongle does not have a ST-Link interface, but the STM32WB has a built-in boot-loader (BTW you can flash the Nucleo Board in the same way). I use the CLI from the STM32CubeProg package.

$ alias cubepgmcli='/opt/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32_Programmer_CLI'
$ cubepgmcli -c port=USB1 -ob displ
