HI,All
Before I erase flash ,I must do memcpy(). I do not know why.
As follow, after i delete the function memcpy( (uint8_t*)&data_buff[0], pdata, len), when i write data[8]={0x01,02,03,04,05,06,07,08} to flash, I see the memory is 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00 by debug.
Can you tell me why i must do memcpy();
I use sdk 12.3 , fs to do the flash reading and writing.
Thanks.
void my_fs_update(uint8_t * pdata, uint16_t len) { fs_ret_t ret; len = len>8?8:len; memcpy( (uint8_t*)&data_buff[0], pdata, len); ret = fs_erase(&fs_config, fs_config.p_start_addr, 1, NULL); if ( FS_SUCCESS != ret ) { printf("fs erase err\r\n"); } }
