这是我的测试代码： void NAND_Erase_Chip(void) { HAL_StatusTypeDef err_code = HAL_OK; NAND_AddressTypeDef addr = {0}; for(uint16_t i = 0; i < nand_dev.block_totalnum; i++) { addr.Block = i; printf("Erase block %d\r\n", i); err_code = HAL_NAND_Erase_Block(&hnand1, &addr); if(err_code) { printf("Erase %d block fail!! Error code is %d\r\n", i, err_code); } } } uint8_t Test_Read_Page(uint16_t block_num, uint16_t page_num) { static uint8_t first_time_exe = 0; uint8_t *pbuf; uint8_t sta = 0; uint16_t i = 0; NAND_AddressTypeDef addr = {0}; addr.Block = block_num; addr.Page = page_num; printf("\r\n ========Read block %d page %d ========\r\n", block_num, page_num); if(first_time_exe == 0) { // printf("Start to erase chip...\r\n"); // NAND_Erase_Chip(); // printf("Erase chip finished...\r\n"); printf("Start to erase block %d...\r\n", block_num); sta = HAL_NAND_Erase_Block(&hnand1, &addr); if(sta) { printf("Erase block failed...\r\n"); } else { printf("Erase block finished...\r\n"); } first_time_exe = 1; NAND_Delay(100); } pbuf = My_Malloc(SRAM1, hnand1.Config.PageSize); sta = HAL_NAND_Read_Page_8b(&hnand1, &addr, pbuf, 1); if(sta == HAL_OK) { printf("read block %d page %d data is: \r\n", addr.Block, addr.Page); for(i = 0; i < hnand1.Config.PageSize; i++) { printf("%x ", pbuf); } printf("\r\n"); } My_Free(SRAM1, pbuf); return sta; } uint8_t Test_Write_Page(uint16_t block_num, uint16_t page_num) { uint8_t *pbuf; uint8_t sta = 0; uint16_t i = 0; NAND_AddressTypeDef addr = {0}; pbuf = My_Malloc(SRAM1, hnand1.Config.PageSize); addr.Block = block_num; addr.Page = page_num; for(i = 0; i < hnand1.Config.PageSize; i++) { pbuf = i; } printf("Start to write page...\r\n"); sta = HAL_NAND_Write_Page_8b(&hnand1, &addr, pbuf, 1); printf("Write page finished. Error code is %d\r\n", sta); My_Free(SRAM1, pbuf); return sta; } void Test_Nand(void) { NAND_IDTypeDef pNAND_ID; HAL_NAND_Reset(&hnand1); HAL_NAND_Read_ID(&hnand1, &pNAND_ID); printf("NAND ID is: 0x%x-%x-%x-%x\r\n", pNAND_ID.Maker_Id, pNAND_ID.Device_Id, pNAND_ID.Third_Id, pNAND_ID.Fourth_Id); Test_Read_Page(10, 10); Test_Write_Page(10, 10); printf("Read data again...\r\n"); Test_Read_Page(9, 9); Test_Read_Page(10, 10); Test_Read_Page(11, 11); }
