Hello,

I'm trying to write 8 Bytes in UserData flash but function MSC_ErasePage always return mscReturnLocked.

Setup :

• BGM320PA22JIA
• SDK v3.0.2
• Custom board
• Software configured with slcp file on SS v5

Code :

#include "em_device.h"
#include "em_msc.h"

int8_t flash_save(bd_addr addr)
{
	MSC_Status_TypeDef retval;
	int8_t err = -1;
	uint32_t data[2];

	data[0] = addr.addr[0] | addr.addr[1] << 8 | addr.addr[2] << 16 | addr.addr[3] << 24;
	data[1] = addr.addr[4] | addr.addr[5] << 8;

	MSC_Init();


	retval = MSC_ErasePage((uint32_t*) USERDATA_BASE); //Always return mscReturnLocked

	if(retval == mscReturnOk)
	{
		retval = MSC_WriteWord((uint32_t*) USERDATA_BASE, data, sizeof(data));
		if(retval != mscReturnOk)
			err = -1;
        else
            err = 0;
	}
	MSC_Deinit();

	return err;
}

Thanks in advance for your help.
Regards,

Gabriel
