hal_flash_device.c::snor_device_verify_erase() currently modifies the state of BaseFlash::state in the case of an error in verifying. However, this is not necessary, as the hal_serial_nor::snor_verify_erase() (which is the function in the BaseFlash VMT) already manages the state of BaseFlash::state ...

The BaseFlash:state should be able to be read without having to use flash(Acquire/Release)Exclusive in the case of multiple threads using the same BaseFlash. Normally, this isn't a problem - but erase operations can take a long time during which the thread managing the erase may want to get exclusiv...

Everywhere I look, I wonder if the thing was generated with ChatGPT lol.

Some additional drivers .. ADC, EFL, and GPT.

EFL is basically a special case of the BaseFlash simulation driver:

Most drivers do not use the DMA FIFO, some do: SDIOv1, SDMMCv1, CRYPv1, QUADSPIv2 . Is there any logic behind why some enable it and others don't? Recently had an issue where we were getting dma errors while using external SRAM, and SPI DMA with that external SRAM. Enabling DMA FIFO solved the probl...

I've been making use of the simulator port quite a bit, and now need to be able to run simulation on something like a raspberry pi.

The current simulation port is for x86. Any hope you can make a port for armv7-A and armv8-A (I think they may be identical?).

Of course the snor erase range code I provided was buggy, lol. I updated the first post with a hopefully corrected version - but anyways, you get the point.

Just thinking about it, the callback should include the number of bytes erased thus far. That should do it ... the application would know the progress as it provided the erase range to begin with.

This is a lightweight layer to register BaseFlash devices along with partitions for the application layer. This allows the application to address/access a particular partition of a particular device with path like "sda1/config". This is useful, and probably all most embedded applications n...

Here's one that specific for EFL - which can be added to os/hal/ports/simulator/posix. It's very similar. A notable difference is that this has a flash_descriptor_t that is defined in the LLD driver itself (configurable via preprocessor symbols) - as opposed to the generic driver above which expects...
