Memory and QSPI flash configurations

tsung-chihwang — Mon, 04 Mar 2019 05:31:47 GMT

Hi, below are our platform information.

1. chip set: IMX6ULL

2. BSP version: 4.1.15-2.1.0

We try to boot from QSPI flash. (boot ROM--> u-boot--> Linux kernel)

Should we need to do some configurations for QSPI flash and DDR3 memory?

If the answer is yes, I was wondering if you could point out where and how to modify them.

BR,

carter

Hi Tsung-Chih

main points may be mfg tool qspi vbs script like mfgtool2-yocto-mx-evk-qspi-nor-n25q256a.vbs

and qspi configuration file, like qspi-nor-macronix-mx25l51245g-config

i.MX Series Manufacturing Toolkit for Linux 4.1.15_2.1.0 Release

described in sect.8.6.3 QuadSPI configuration parameters i.MX6ULL Reference Manual

http://www.nxp.com/docs/en/reference-manual/IMX6ULLRM.pdf

For memory use ddr test and update image with new calibration coefficients (uboot/../mx6ullevk/imximage.cfg)

i.MX6/7 DDR Stress Test Tool V3.00

Hi Igor,

Thanks for your help so much.

I have another one question.

How to choose the proper QSPI configuration file?

We selected the qspi-nor-micron-n25q256a-config file for Micron Serial NOR Flash Memory "N25Q512A"

It seems can work fine.

However, we will have another two flashes "MT25QL01GBBB" and "MT25QL02GC" soon, which configuration file can be used for these two flashes?

BR,

carter

You may try using existing configuration files however you will most probably have to create your own configuration for those two flash chips. The parameters are explained in section 8.6.3 QuadSPI Configuration Parameters of i.MX6ULL Reference Manual as Igor stated before.

Hi Carter

configs files should be created using datasheets of used qspi parts,

use qspi-nor-micron-n25q256a-config as example. In general nxp

has special service for helping customers with software customizations:
