2. Bootloader 对 Application 的升级操作,底层调用的操作函数是 CySysFlashWriteRow(), 该函数的功能解释是 “Write row erases and then programs the addressed row of non-privileged FLASH, with data in the page latch buffer. If all data in the page latch buffer is 0, then the program is...
✅ Flash Drive Must be Formatted but will Erase all data:I don't know how my flash drive became "read only" but every time I try to access it it says i need to format it and by doing so it will erase data. I...
stm32 FLASH_EraseSector函数 最开始用stm32的flash保存数据的方法都是用原子的例程,STM32F1的话,原子的方法大概是创建一个1K或者2K的缓存,修改数据的时候,先把该扇区的所有数据写到该缓存,然后查看是否需要擦除整个扇区,一般在一个地方写的话,必须要擦除,要想不擦除,就需要一个变量记录下一次要写的地址,和...
J-Flash Version: V7.94g Firmware code: just empty main code S32DS version: S32DS 3.5 RTD version: 4.0.0 We are using our own board, so I wanna know how to unlock the sector to erase or program the sector, because I can successful connect the s32k311 mcu. When using Jlink to burn...

The second attempt revealed that it wasn't because of Erase/Write to protected sector.We speculate that it is due to Program or erase targeting PFlash with active Safety ENDINIT protection.So we made a third attempt:1.Read FSR reg, read value=0x01002000.2.Read WDTSCON...
In operation, when a host needs to read data from or write data to the flash memory, it will communicate with the flash memory controller. If the host provides a logical address to which data is to be read/written, the flash memory controller can convert the logical address received from ...
