GD flash for imx6ull

frank_chiang — Wed, 13 Jun 2018 13:55:11 GMT

I would like use GD flash(GD25q32CSIGR) on IMX6ULL(MCIMX6Y2CVM08AB) and base on yocto-L4.1.15_2.0.0.

Because IMX6ULL does not support GD flash now. Does anyone have an idea how to do it?

Hi frank

chip specific parameters should be added to

uboot/drivers/mtd/spi/sf_params.c
linux/drivers/mtd/devices/

please also check below patch and attached Porting Guide

mtd: chips: Add support for GigaDevice GD25Q32/GD25Q64 SPI Flash in m25p80.c - Patchwork

Best regards

hi, Igorpadykov

Because of our image created by freertos project like "hello world", and we would like to use mfgtool to program into GD flash(GD25q32CSIGR).

Following is my step to recompile mfgtool.

Using below command to get mfgtool package
bitbake fsl-image-mfgtool-initramfs
Modify spi-nor.c located in tmp/work/imx6ull14x14evklevk-poky-linux-gnueabi/mfgtool-linux-imx/4.1.15-r0/git/drivers/mtd/spi-no as below/* GigaDevice */
{ "gd25q32", INFO(0xc84016, 0, 64 * 1024, 64, SECT_4K) },
Modify sf_params.c located in tmp/work/imx6ull14x14evk-poky-linux-gnueabi/u-boot-imx-mfgtool/2016.03-r0/git/drivers/mtd/spi as below.

#ifdef CONFIG_SPI_FLASH_GIGADEVICE /* GIGADEVICE */
{"GD25Q32", 0xc84016, 0x0, 64 * 1024, 64, RD_NORM, SECT_4K}

Modify mx6ullevk.h located in tmp/work/imx6ull14x14evk-poky-linux-gnueabi/u-boot-imx-mfgtool/2016.03-r0/git/include/configs as below. #define CONFIG_SPI_FLASH_STMICRO ==> #define CONFIG_SPI_FLASH_GIGADEVICE
$ bitbake -c compile -f linux-mfgtool
$ bitbake fsl-image-mfgtool-initramfs

After finishing all steps, it doesn't create any new deploy files in deploy-u-boot-imx-mfgtool and deploy-meftool-linux.

Did I do something wrong? So it can't create new deploy files.

I try to update these deploy files to mfgtool folder as below to support program image into GD flash(GD25q32CSIGR).

Hi frank

basic steps for bulding mfg tools firmware are described in Yocto Guide

sect.6.2 Manufacturing Tool, MFGTool included in Linux documentation on

https://www.nxp.com/support/developer-resources/run-time-software/i.mx-developer-resources/i.mx-6series-i.mx-7series-software-and-development-tool-resources:IMX_SW

linux-imx - i.MX Linux kernel

hi igor

Now I downloaded the new yocto version (yocto-L4.1.15_2.1.0.)

Then I use bellow steps to modify some code in mfgtool floders including mfgtool-linux-imx and u-boot-imx-mfgtool.

My target is to program image to GD flash(GD25q32CSIGR) by modified mfgtool tool.

$repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth -m imx-4.1.15-2.1.0.xml
$ repo sync
$ bitbake fsl-image-mfgtool-initramfs
modify spi.c at tmp/work/imx6ull14x14evklevk-poky-linux-gnueabi/mfgtool-linux-imx/4.1.15-r0/git/drivers/mtd/spi-nor
/* GigaDevice */
{ "gd25q32", INFO(0xc84016, 0, 64 * 1024, 64, SECT_4K) },
modify sf_params.c in tmp/work/imx6ull14x14evk-poky-linux-gnueabi/u-boot-imx-mfgtool/2016.03-r0/git/drivers/mtd/spi
#ifdef CONFIG_SPI_FLASH_GIGADEVICE /* GIGADEVICE */
{"GD25Q32", 0xc84016, 0x0, 64 * 1024, 64, RD_NORM, SECT_4K},
modify mx6ullevk.h in tmp/work/imx6ull14x14evk-poky-linux-gnueabi/u-boot-imx-mfgtool/2016.03-r0/git/include/configs
#define CONFIG_CMD_SF
#define CONFIG_SPI_FLASH
#define CONFIG_SPI_FLASH_BAR
#define CONFIG_SF_DEFAULT_BUS           0
#define CONFIG_SF_DEFAULT_CS            0
#define CONFIG_SF_DEFAULT_SPEED 40000000
#define CONFIG_SF_DEFAULT_MODE          SPI_MODE_0
#define CONFIG_SPI_FLASH_GIGADEVICE
bitbake -c compile -f mfgtool-linux-imx
bitbake -c compile -f u-boot-imx-mfgtool
bitbake fsl-image-mfgtool-initramfs
copy below files and rename into mfgtools\Profiles\Linux\OS Firmware\firmware
u-boot-mfgtool-2016.03-r0.imx -> u-boot-imx6ull14x14evk_qspi1.imx
zImage

follow 5.2 Using Manufacturing Tool (MFGTool) in Getting Started with MCUXpresso SDK for i.MX 6UltraLite Derivatives.pdf to program image to GD flash.
restart board.

But it is doesn't work. Attached is log file.

Do you have any idea how to solve this issue and make image programmed into GD flash?

Hi frank

in attached log there are no any error messages, is this flash working fine in uboot ?

hi igor

How can I check flash is working fine on u-boot?

After freertos hello world project was compiled, I just used mfgtool to program bin file to GD flash.

It didn't output anything from uart.

If I program bin file on micron and use original mfgtool , it can output "hello world" from uart.

Attached, GD0626.txt, is created by mfgtool during program bin file.

>How can I check flash is working fine on u-boot?

boot uboot from sd/emmc or other media. Check spi-nor with

uboot commads:

sf probe

sf erase

sf write

check uboot documentation for spi-nor commands.
