STM32G4 external loader

Job ID: 38938608

Budget: $30 – $250 USD

I am looking for a person to make a firmware external loader for the STM32G491RE microcontroller. The external loader should work in QSPI mode with W25Q128 memory.
Development environment: STM32CubeIDE 1.17.0 or later.
Programmer/debugger: ST-LINK-V2.
Język programowania: C
Biblioteki: HAL

Note! I tested the external loaders available on the Internet. If I use classically Init(), Erase(), Write() functions work correctly. But the external loader with these functions does not want to work. Probably it is a problem of STM32CubeIDE configuration or or GDB server or ST-LINK.

I do not have relevant experience. I am looking for someone who is able to make a loader for this particular configuration.
