Getting StartedThese instructions will get you a copy of the project up and running on your local machine (STM's NUCLEO-H743ZI board) for development and testing purposes.Prerequisites

Additional Tools and Local FilesystemPopulate a microSD with the contents of sdcard. Put the microSD into the H743 slot and reset or power cycle the board. The directory should look like this:ls -l 1:[CR] drw- 0 2021-04-18T18:12:38 boot drw- 0 2021-03-21T18:47:52 etc drw- 0 2021-03-21T18:47:54 fsr drw- 0 2021-03-21T18:47:54 home drw- 0 2021-03-21T18:47:56 man -rwa 7219 2021-01-08T19:42:36 README.md ok.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 2 Minutes):
dd 1:/boot/fd-2MiB.img 0:[CR] ok. mount 0:[CR] ok. ls 0:[CR] man fsr README.md boot etc home ok.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:

InstallingA step by step series of examples that tell you how to get a development env running Install the IDE STM32CubeIDE, it is Eclipse and GCC based. STM32CubeMX is included in the IDE, you need a stand alone installation only if you do not want to use the STM32CubeIDE.

STM32H747 Arduino Portenta H7 Development BoardThis Arduino Portenta H7 development board follows the Arduino MKR form factor, but enhanced with the Portenta family 80 pin high-density connector. Why should I use this board? It is less powerful than a Raspberry Pi and is even more expensive! The Raspi draws much more current and therefore cannot be operated with a battery. No Board Support Package yet. https://docs.arduino.cc/hardware/portenta-h7 Schematics The much smaller board Arduino Nicla Vision equipped with a 2MP camera.Wio Lite AI Single BoardNo Board Support Package yet.This work by Peter Schmid is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.
