Using a different nor flash chip with ls1021a twr board

sujay1 — Fri, 04 Sep 2020 11:13:14 GMT

I'm using a custom board based on ls1021a-twr board,

The reference board uses mt28ew01gaba1hjs-0sit as the nor flash chip connected to the ifc bus,

But the custom board uses is29gl256-70flet,

what changes should I make to the source?

It is needed to download datasheets of both NOR Flash devices, compare them and accordingly modify the board's header file, for example 'ls1021atwr.h':

Hi Ufedor,

Thanks for the support, However it's unclear what I need to change could you give me an example of a field I should modify?
