Posted on January 27, 2016 at 01:00Hello!!
The flash erase time may be about below 100ms on the code of My predecessor.
But the erase time of my code is over 2sec like the above table.
I think that there may be any setting to reduce the erase time.
My predecessor and I use the same code to erase the flash like below.
--------------------------------------------------------------------------------
int8_t FLASH_If_Erase(uint32_t StartSector)
{
uint32_t FlashAddress;
FlashAddress = StartSector;
/* Device voltage range supposed to be [2.7V to 3.6V], the operation will
be done by word */
if (FlashAddress <= (uint32_t) USER_FLASH_LAST_PAGE_ADDRESS)
{
#ifndef USE_GES_MEM_CONFIG
//FLASH_EraseSector(FLASH_Sector_4, VoltageRange_3); /* 64 Kbyte */
//FLASH_EraseSector(FLASH_Sector_5, VoltageRange_3); /* 128 Kbyte */
FLASH_EraseSector(FLASH_Sector_6, VoltageRange_3); /* 128 Kbyte */
FLASH_EraseSector(FLASH_Sector_7, VoltageRange_3); /* 128 Kbyte */
//FLASH_EraseSector(FLASH_Sector_8, VoltageRange_3); /* 128 Kbyte */
//FLASH_EraseSector(FLASH_Sector_9, VoltageRange_3); /* 128 Kbyte */
//FLASH_EraseSector(FLASH_Sector_10, VoltageRange_3); /* 128 Kbyte */
//FLASH_EraseSector(FLASH_Sector_11, VoltageRange_3); /* 128 Kbyte */
#else
FLASH_EraseSector(FLASH_Sector_6, VoltageRange_3); /* 128 Kbyte */
FLASH_EraseSector(FLASH_Sector_7, VoltageRange_3); /* 128 Kbyte */
#endif
}
else
{
return (1);
}
--------------------------------------------------------------------------------
How can I reduce the erase time?
Is there any setting to do that?
Thanks.
I want to reduce the erase time into about 100ms ~ 300ms.How can I do it?..Thanks.
