i.MX RT series Flexspi Nor ROM APIs Usage & Flashloader

 

i.MXRT系列具有内部ROM,并且ROM中暴露出了一些功能接口可供用户直接使用。

本文介绍了Flexspi Nor ROM APIs, 并且列举了API相关的参数及示例程序。

通过这些API可以很方便的操作外部Flexspi Nor Flash。用户无需关系细节。

Hi @daweiyou ,

Many thanks for your sharing, the document is helpful.

There is an question, please help.

Is there any internal memory region of RAM MUST reserved for ROM APIs when we use it in the application?

My use platform is i.MXRT1170.

Thanks.

David

Hi David:

 

In RM and other documents, I have no seen any notes about fixed memory used by ROM api.

But I think Stack should be needed during ROM api calling.

I ever try use minimum stack size, ~1KB is allocated during some SDK example case, but Flexspi ROM API fails.

I don't know the extra stack size needed by ROM API, but I think normal stack size(> several KB size) should be OK.

Hi Dawei,

Many thanks for your input.

David
