Flash memory parameters in Nordic nRF52840

[embedded717]

Is there a block header information available that I can read thru the flash read function (e.g. in ble_flash driver, ble_flash_page_read() function ) ? My FS (file system) requires block header info to be read from the flash device.

Block header info would have something like block number, id, size, crc etc.

Hi

The FICR contains various registers related to the chip type, memory configuration and so forth.

The FICR starts at memory address 0x10000000, and you can find the full list of registers described in the nrF52840 OPS.

In particular the CODEPAGESIZE and CODESIZE registers sound relevant for you.

Best regards
Torbjørn

Is there a FS (file system) example I can adopt in the SDK13 ? I need fs_init, read, write etc.

Yes, we have a port of the FAT file system in SDK13, including an example located here:
