【BUG】9218烧写flash例程连续烧写后无法对芯片进行烧录
Sep 22, 2022 16:02
flash例程连续烧写两次以后，可以active，但是一直烧写失败。
具体操作为：连续烧写，但是中间没有点击active和sws
已经在两个板子上复现了，现在不敢重试了。。。
修改了user_init部分的代码：
void user_init()
{
// int i;
delay_ms(1000);
uart_debug_init();
mid = flash_read_mid();
// flash_erase_sector(FLASH_ADDR);
// flash_read_page(FLASH_ADDR,FLASH_BUFF_LEN,(unsigned char *)Flash_Read_Buff);
// for(i=0; i<FLASH_BUFF_LEN; i++){
// if(Flash_Read_Buff[i] != 0xff){
// err_status.erase_err = 1;
// while(1);
// }
// }
// check_status.erase_check = 1;
// printf("flash erase down!\n");
//
// flash_write_page(FLASH_ADDR+0x80,FLASH_BUFF_LEN,(unsigned char *)Flash_Write_Buff);
// flash_read_page(FLASH_ADDR+0x80,FLASH_BUFF_LEN,(unsigned char *)Flash_Read_Buff);
// for(i=0; i<FLASH_BUFF_LEN; i++){
// if(Flash_Read_Buff[i] != Flash_Write_Buff[i]){
// err_status.write_err = 1;
// while(1);
// }
// }
// check_status.write_check = 1;
Flash_Write_Buff[2] = 0x99;
Flash_Write_Buff[3] = 0x89;
// flash_write_page(FLASH_ADDR+0x80,FLASH_BUFF_LEN,(unsigned char *)Flash_Write_Buff);
flash_read_page(FLASH_ADDR+0x80,FLASH_BUFF_LEN,(unsigned char *)Flash_Read_Buff);
printf("flash erase down0:%x %x!\n", Flash_Read_Buff[2], Flash_Read_Buff[3]);
flash_erase_sector(FLASH_ADDR);
flash_write_page(FLASH_ADDR+0x80,FLASH_BUFF_LEN,(unsigned char *)Flash_Write_Buff);
flash_read_page(FLASH_ADDR+0x80,FLASH_BUFF_LEN,(unsigned char *)Flash_Read_Buff);
printf("flash erase down1:%x %x!\n", Flash_Read_Buff[2], Flash_Read_Buff[3]);
#if (MCU_CORE_B91)
switch(mid)
{
case 0x146085:
// flash_mid146085_test();
break;
default:
break;
}
#endif
check_status.umid_check = flash_read_mid_uid_with_check((unsigned int *)&mid, uid);
}

新的BDT 有个unlock，unlock以后可以用了
