Hi,

Sector code is the number of the sectors , for example if you want to Erase 4 first sectors, you need to send the their numbers : 0 , 1 , 2, 3. as in our Reference Manual for STM32F405/407 of that discovery RM0090.

Check also if it is an Erase 0x43 or Extended Erase 0x44 in AN2606/AN3154.

Cheers,

I write like this to erase 4 first sectors but not working...

hcan.pTxMsg->StdId = 0x43;

hcan.pTxMsg->RTR = CAN_RTR_DATA;

hcan.pTxMsg->IDE = CAN_ID_STD;

hcan.pTxMsg->DLC = 4;

hcan.pTxMsg->Data[0] = 0x00;

hcan.pTxMsg->Data[1] = 0x01;

hcan.pTxMsg->Data[2] = 0x02;

hcan.pTxMsg->Data[3] = 0x03;

HAL_CAN_Transmit(&hcan, 10);
