Got an F769 Disco board, and finally was able to get better test coverage with a device with non-uniform sector sizes. Of_course it uncovered some bugs :). Updates below: /** * @brief Get absolute address from offset * * @param[in] ip pointer to a @p BaseFlash or derived class * @param[in] offset of...

STM32 EFL drivers shouldn't to write to flash if the entire page the user wants to write contain 1s. On the STM32, if you write to a page - even if it is all 1s and did not change the state of flash, it generates a page write error on a subsequent write. On some devices, the flash memory will allow ...

Is hal_mfs compatible with page sizes > 8 bytes? Asking because I noticed H7 series has up to 32 byte page size.

Updated to support all known version of STM32F7xx . There, I guess that's done now

https://github.com/faisal-shah/ChibiOS. ... efl_20.3.x

Updated with F730x support.

I tested it with the MFS test suite. See the attached patch. Based off of latest from stable_20.3.x *** ChibiOS/HAL MFS Test Suite *** *** Compiled: Dec 17 2021 - 19:56:25 *** Platform: STM32F722 Very High Performance with DSP and FPU *** Test Board: STMicroelectronics STM32 Nucleo144-F722ZE *** ***...

Now it is tested (fixed a few bugs) but only the descriptor->sectors == NULL path (uniform sector sizes). I also added some more helpful functions that are commonly needed when interacting with hal-flash. /** * @brief Get absolute address from offset * * @param[in] ip pointer to a @p BaseFlash or de...

A small update: flash_sector_t flashGetOffsetSector(BaseFlash *devp, flash_offset_t offset) { flash_sector_t sector; const flash_descriptor_t *descriptor = flashGetDescriptor(devp); osalDbgAssert(offset > ((flash_offset_t)descriptor->address + descriptor->size), "invalid offset"); if (desc...
