NANDFLASH status enumerator. More... | |
Functions | |
bool | NANDFLASH_AddressValid (uint32_t addr) |
Check if an address is valid for the nand flash device. More... | |
int | NANDFLASH_CopyPage (uint32_t dstAddr, uint32_t srcAddr) |
Copy a page within the device to a new location. More... | |
NANDFLASH_Info_TypeDef * | NANDFLASH_DeviceInfo (void) |
Return a pointer to a NANDFLASH_Info_TypeDef structure, which contain vital nand flash device information. More... | |
int | NANDFLASH_EccCorrect (uint32_t generatedEcc, uint32_t readEcc, uint8_t *data) |
Check generated ECC against ECC read from device and correct data if possible. More... | |
int | NANDFLASH_EraseBlock (uint32_t address) |
Erase a block in the nand flash. More... | |
int | NANDFLASH_Init (int dmaCh) |
Initialize the NANDFLASH module. More... | |
int | NANDFLASH_MarkBadBlock (uint32_t address) |
Mark a block as bad. More... | |
int | NANDFLASH_ReadPage (uint32_t address, uint8_t *buffer) |
Read a page from nand device. Ecc errors will be detected and corrected if possible. NANDFLASH_Info_TypeDef::ecc will be set to the ecc generated while reading the page data. NANDFLASH_Info_TypeDef::spare will be set to the content of the page spare area. More... | |
int | NANDFLASH_ReadSpare (uint32_t address, uint8_t *buffer) |
Read the spare area content of a page. More... | |
int | NANDFLASH_WritePage (uint32_t address, uint8_t *buffer) |
Write a page in nand device. The ECC generated while writing the page data is written in the spare area at byte positions 7, 8 and 9. More... | |
