Embedded erase failure in NOR flash EEPROM memory

WebI had to remove the const from the declaration to make it work. My complete solution consists of two parts (as already said above but with some further modifications): FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 896K /* origin size was 1024k, subtracted size of DATA */ DATA (rx) : ORIGIN = 0x080E0000, LENGTH = 128K. Web\$\begingroup\$ @JoelFernandes Although you technically could design a NOR flash to be capable of individual cell erasure, that's not done in practice. Because it requires a high negative voltage, not a 0 or a 1, to erase a cell, they link many cells up into blocks to perform this erase operation. ph wert und wassertemperatur
