LPC54608 flashiap

実奥山 — Sun, 02 Dec 2018 03:03:38 GMT

I wrote the MAC address in flash using flashiap.

Below was made based on a sample of NXP.

MAC address was included in page_buf, and copied this in a flash.

But I don't understand the way to read this data from a flash.

Please tell me the way to read data of a flash using flashiap.

    /* Program sector */
    for (i = 0; i < (FSL_FEATURE_SYSCON_FLASH_SECTOR_SIZE_BYTES / FSL_FEATURE_SYSCON_FLASH_PAGE_SIZE_BYTES); i++)
    {
        FLASHIAP_PrepareSectorForWrite(7, 7);
        FLASHIAP_CopyRamToFlash(
            //FSL_FEATURE_SYSCON_FLASH_SECTOR_SIZE_BYTES + (i * FSL_FEATURE_SYSCON_FLASH_PAGE_SIZE_BYTES), &page_buf[0],
            0x38000 + (i * FSL_FEATURE_SYSCON_FLASH_PAGE_SIZE_BYTES), &page_buf[0],
            FSL_FEATURE_SYSCON_FLASH_PAGE_SIZE_BYTES, SystemCoreClock);
    }

I can read data by below(flashdata).

const unsigned char flashdata= *(unsigned char *)0x038000;

I use LPC54608J512 and this device have 512K flash(0 to 15 sectors).

But I can not access 8 to 15 sectors.

Please teach me how to access 8 to 15 sectors.

Hi Customer,

Yes, if you want to read the flash data, just read that address's data is OK.

You said, you can't access 8 to 15 sectors, please check, do you control the correct address?

Have a great day,
Kerry
