erase 256 sectors in one time
Posted: Sat Nov 14, 2015 2:06 amI want to erase 256 sectors in a loop. And I have disabled the wdt using pp_soft_wdt_stop and pp_soft_wdt_restart.
But the chip reboot randomly in the loop.
Here is my code
And there is serial output
Even I delay 100000us is not help. Sometime the sector number will up to 81.But total is 256.
So what is the problem
But the chip reboot randomly in the loop.
Here is my code
Code: Select all
#define COFFEE_START 0x200000UL
#define COFFEE_SECTOR_SIZE 0x1000UL
pp_soft_wdt_stop();
for(i = 0; i < COFFEE_SECTOR_COUNT; i++) {
printf("%d\n",i);
//clock_delay(100000UL);
while(SPI_FLASH_RESULT_OK!=spi_flash_erase_sector((uint16)((COFFEE_START/COFFEE_SECTOR_SIZE)+(i))));
}
pp_soft_wdt_restart();And there is serial output
Code: Select all
format: formatting file system, please wait...
