Petalinux 2015.4 - Adding Flash Parts into sf_params.c

Good Day Everyone,


I am currently facing an issue where U-Boot isnt able to detect (through sf_probe) my QSPI flash (Micron - N25Q00). After finding solutions on the web, i realised new Flash Parts can be added into sf_params.c to allow the U-boot to recognise the Flash part. The question is regarding how do i know that the U-BOOT that is rebuild is using the newly saved sf_params.c and not using the previous sf_params.c instead? Up till now i was not able to figure out whether the new sf_params.c isnt taking effect or i have entered the wrong parameters for the flash part inside sf_params.c. I am developing the project using Vivado 2015.4 on a KINTEX7 custom board using a microblaze processor and axi_quad_spi ip core.

Error reported during sf_probe:
SF : Unsupported Flash IDs: manuf 10, jedec dd10, ext_jedec 0800
Failed to initialize SPI flash at 0:0 (error -22)

Is there anyway to decode what the error -22 is refering to?
Any help would be nice.. thanks in advance!
