When writing to flash on a STM32G031 Page erase enable occasionally causes hardfault
When writing to flash on an STM32G031 microcontroller, the “Page erase enable” bit is used to enable page erase operations in the flash memory. This bit must be set in order to perform page erase operations.
A hardfault can occur when writing to flash memory if there is an issue with the memory access, alignment, or timing. There are a few things you can do to troubleshoot this issue:
-
Ensure that you are correctly configuring the flash memory for the specific STM32G031 device you are using. The device reference manual and datasheet should provide guidance on how to do this.
-
Check that the memory access is properly aligned. Writing to flash memory requires specific memory alignment, and attempting to write to unaligned memory can cause a hardfault. The flash memory on the STM32G031 requires 32-bit alignment for write operations.
-
Verify that you are following the correct sequence of steps for writing to flash memory. The STM32G031 requires a specific sequence of instructions to write to flash memory, and deviating from this sequence can cause a hardfault.
-
Check the timing of your flash memory write operations. If you are writing to flash memory too quickly or too slowly, this can cause a hardfault. Refer to the device reference manual for guidance on the appropriate timing for flash memory write operations.
If you continue to experience hardfaults when writing to flash memory on the STM32G031, you may want to consider using a debugger to step through your code and identify the specific point at which the hardfault occurs. This can help you pinpoint the issue and resolve it more quickly.
