Posted on March 17, 2017 at 23:00Hi!
I am trying to write s string into the EEPROM of a STM32L053.
I create a strcpy like funtion, using STM32L0xx HAL Libraries:
for writing the EEPROM I use this sequence of HAL functions.
char ascii_string[200];
HAL_FLASHEx_DATAEEPROM_Unlock( );
HAL_FLASHEx_DATAEEPROM_Program( FLASH_TYPEPROGRAMDATA_BYTE, ( uint32_t ) dest_addr , ascii_string[0] );
HAL_FLASHEx_DATAEEPROM_Program( FLASH_TYPEPROGRAMDATA_BYTE, ( uint32_t ) dest_addr + 1 , ascii_string[1] );
...
HAL_FLASHEx_DATAEEPROM_Program( FLASH_TYPEPROGRAMDATA_BYTE, ( uint32_t ) dest_addr + N-1, ascii_string[N-1]);
HAL_FLASHEx_DATAEEPROM_Lock( );
This works OK while debugging step by step, but when I run this freely, it goes to FaultHandler (and the write protect flag is ON).
I am using the 1.8 version of the HAL library.
I think is some timing issue. Could be something in regard the clock speed? (I am using 32MHz) .
Any help will be apreciated.
Thanks.
