How to modify Flash driver FLM file for RT1062?

[John-Madison]

Hello,

I am using a custom board that only has two data pins connected to Quad SPI Flash. Because of this the standard flash driver (Arm\Packs\NXP\MIMXRT1062_DFP\16.0.0\arm\MIMXRT106x_QSPI_4KB_SEC.FLM) doesn't work for me. 

Can anyone point me to where I can locate the source code for this project?  

Thanks!

John

Hello Mike,

I first asked this question in the Keil forums, and I was told there by Keil technical support  that the Device Pack is provided by NXP and that I should ask here.

https://community.arm.com/support-forums/f/keil-forum/54249/mimx-rt1060-flm-source:

"John, the corresponding Device Family Pack is provided by NXP. And as (atm) these Packs do not include the projects to generate the Flash Programming Algorithms, I recommend getting in contact with NXP Support directly"

I also found the 105x project, but because it is a different processor and different flash technology, the project is quite different that what I need.

Thanks,

John

Hello John,

I got one FLM project for RT1170 product, which is also suitable for the RT106x product.

About Keil FLM, you only need to write below functions:

 init, Uninit(not neccessary), EraseChip(Not neccessary), EraseSector, ProgramPage and also the Verify.

I attached the project for your reference.

Wish it helps.

Thanks, this helped me a lot to be able to flash my rt1176 at flexSPI2 Port B!

But i have some strange behavior. I've got an offset of 2 bytes in the written and read data from the flash.

Any ideas where that might be coming from?

I used the same version of the SDK as you and haven't modified the code other than changing the flash base address and the other flags needed to use flexSPI2 Port B.

Every idea is appreciated.

Hi John,

Sorry for the later reply.

Unfortunately, I could not find related project at Keil provided RT106x product packages.

I could find a similar project [MiMXRT105x_ATXP032] located at "C:\Keil_v5\ARM\Flash" folder.

Could you check with Keil if they could provided your requested <MIMXRT106x_QSPI_4KB_SEC.FLM> related project? Thanks.

best regards,

Mike
