Hi folks, I have encountered a problem with the STM32 flash driver on revision Z devices. According to the errata document, the debug registers cannot be accessed from the processor on rev-Z devices This means that it it not possible to get the device type by reading CYGHWR_HAL_STM32_MCU_ID, which causes the flash driver to use invalid parameters. Maybe it would be better to rely on the HAL configuration for this information.
I also noticed that the flash and RAM size definitions stored in the CYGHWR_HAL_STM32_DEV_SIG register are the wrong way round for my device (ie, the _FSIZE macro gets the RAM size and the _RSIZE macro gets the flash size). I don't know if this is an eCos bug or a rev-Z bug, since the documentation for this register seems a bit vague. Chris.
