Generating Flex-SPI Image for OSPI-Flash/QSPI-Flash Memory

[kailas_kharse]

Hello,

We have NXP`s MCIMX8QXP MEK board. We are using the "i.MX Linux Yocto Project BSP 5.4.24_2.1.0 Release".

We are able to generate and boot from the SD card (flashing using dd commands) and eMMC (using serial download mode and UUU utility).

To boot from the onboard micron 64MB octal flash, a bootloader image with FSPI boot support is required. We have some difficulty in understanding the procedure for the following things:

1) Unable to generate the Flex-SPI u-boot binary image. We have followed the procedure as follows:

a) added the UBOOT_CONFIG = "fspi" in local.conf as per procedure given in the i.MX Yocto Project User's Guide and then use command and run the following command:

$bitbake -c cleansstate core-image-base $MACHINE=imx8qxpmek bitbake -c deploy u-boot-imx

Then also, don`t see any flex SPI image generated build/tmp/deploy/images/imx8qxpmek. Here only the sd card image (imx-boot-imx8qxpmek-sd.bin-flash_spl) is getting generated.

2) We have downloaded the Linux prebuild images from the NXP website "L5.4.24-2.1.0_images_MX8QXPC0MEK.zip". In that folder, we found the "imx-boot-imx8qxpc0mek-fspi.bin-flash_flexspi" and "imx-boot-imx8qxpc0mek-fspi.bin-flash_spl_flexspi" images. We tried flashing those images with UUU tool with the following command

$sudo ./uuu -b qspi imx-boot-imx8qxpc0mek-fspi.bin-flash_flexspi

We are getting the following error:

"1:7 1/ 1 [HID(W):LIBUSB_ERROR_IO ] SDPS: boot -f imx-boot-im"

Please guide us on

1) how to generate the flexspi image?

2) How to flash image using uuu into octal flash for the flex interface?

3) Any requirement of "mk-image" here to generate the required images? if yes, How to use to get the required images?

Hi Kailas

1. seems UBOOT_CONFIG = "fspi" is sufficient and other customers successfully built image as on

imx8qxpmek: spi does not work on sd card boot 

2.  for "LIBUSB_ERROR" it is necessary to install libusb library, as described in uuu guide

https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.2.135/UUU.pdf 

3. for "mk-image" one can look at sect.4.5.12 How to build imx-boot image by using imx-mkimage

i.MX Linux User’s Guide

Hello Igor,

I have followed the same process, still I am not able to generate the "imx-boot-imx8qxpc0mek-fspi.bin-flash_flexspi" and "imx-boot-imx8qxpc0mek-fspi.bin-flash_spl_flexspi" images. 

Can you inform what are all the changes need to be done for generating the fspi image?

Please guide how to generate the fspi image, this is major blocker for us.

Below are the list of images generated.
