[imx6] NAND boot must be enable WEIM ?

[yunbaekim]

Hello

I have to use I2C3 for flexCAN.

But I2C3 conflict with WEIM.

So disabled weim

imx6dl-sabreauto-gpmi-weim.dts

and it occured ERROR bellow

I attached 2 Log files.

case1 log file is

     - Disabled i2c3 . Enabled WEIM. =>Booting is success.

case2 log file is

     - Enabled i2c3. Disabled WEIM. =>Booting is fail.

please help...

[andreykononov]

are you solved this problem? i get the same

[andreykononov]

I found a solution

change u-boot cmd for kernel from

console=ttymxc3,115200 ubi.mtd=4 root=ubi0:rootfs rootfstype=ubifs mtdparts=gpmi-nand:64m(boot),16m(kernel),16m(dtb),-(rootfs)

to

console=ttymxc3,115200 ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs mtdparts=gpmi-nand:64m(boot),16m(kernel),16m(dtb),-(rootfs)

Hi yunbaekim

could you try to disable eim also in uboot, undefining

#define CONFIG_SYS_USE_EIMNOR in uboot/include/configs/mx6sabre_common.h

Best regards

igor
