Prerequisites

Changed:
<
<
  • STM32WB Feather Development Board Stackable Feather board with STM32WB55 MCU (Cortex ARM M4) runs at a 32 MHz (the Bluetooth stack runs on a Cortex ARM M0+ core). If you want to debug C and assembler programs you need an ST-Link debugger/programmer.

  • STM32WB5MM-DK Dscovery Kit with STM32W5MMG module, STM32WB55 MCU (Cortex ARM M4) runs at a 32 MHz (the Bluetooth stack runs on a Cortex ARM M0+ core). ST-Link debugger/programmer is integrated on board.
 
  • Terminal emulator application for PC, e.g.:
Line: 61 to 61
  Flash the Mecrisp-Cube binary (MecrispCubeWB5M.bin) or the util-binary (MecrispCubeWB5MUtil.bin) to the Discovery Board.
Changed:
<
<
  1. Connect the Discovery Board USB to the PC
  2. Hold the USR button (BOOTP Pin), push the RES button, release the USR button
  3. Program the binary (MecrispCubeWB5M.bin or MecrispCubeWBfeatherUtil.bin) with the STMCubeProgrammer (select USB Device)
  4. Reset or power cycle the Feather board

>
  1. Connect the Discovery Board USB ST-LINK to the PC
  2. Copy the binary (MecrispCubeWB5M.bin or MecrispCubeWB5MUtil.bin) to the USB mass storage DIS_WB5MMG
  Start the terminal emulator application on the PC. Check for the serial communication port (e.g. for Linux /dev/ttyACM0).

  The directory should look like this:
Line: 126 to 121
 You can use the local CLI commands like mkfs, mkdir and cp to create a filesystem on the serial flash and fill it with files and folders. But this is tedious job because I haven't yet implemented a recursive copy for MecrispCube. But there is prepared disk image (for details see MicroSdBlocks#Serial_Flash) on microSD and the tool dd. You can copy the disk image to the drive 0: (this takes about 8 Minutes):
Changed:
<
<		dd 1:/boot/fd-16MiB.img 0:[CR]

>		dd 1:/boot/fd-1MiB.img 0:[CR]
  ok. mount 0:[CR] ok.
Line: 136 to 131
  ok.
Changed:
<
<		The Mecrisp have some tools bundled in its distribution e.g. assembler, disassembler, dump, float. I put those tools and some more into the folder /fsr. With the "init.fs script" I compile my favorite ones into the flash directory (if you use the util-binary binary, these tools are already compiled in):
