Re: [meta-freescale] MTD UBI undefined reference failed to build OE gatesgarth branch

Thanks for your response. I am sorry, I thought that is what meta-freescale for, right? NXP might involve the coding, but is it integrated and released by Yocto / OE https://git.yoctoproject.org/cgit/cgit.cgi/meta-freescale/, right? I cloned meta-freescale from Yocto project: git://git.yoctoprojec

Re: [yocto] Which recipe for Linux tools to run u-boot command inside Linux?

OK, finally built the u-boot-fw-utils and run it on iMX6ULL: # fw_printenv -v Compiled with U-Boot 2019.07-dirty But it could not run: # fw_printenv Cannot read bad block mark: Invalid argument Here is the configure file: # cat /etc/fw_env.config # NAND /dev/mtd1 0x40

What is the right way to run fw_setenv for selecting different ECC or dtb files?

Hi, To flash u-boot to iMX6ULL NAND, it requires using higher bits ECC (my imx6ulz_kobs.dtb) to run kobs-ng in ramdisk, but to flash rootfs image to NAND in ramdisk, I have to change to use lower ECC (my imx6ulz.dtb). I followed the advice at link https://developer.toradex.com/knowledge-base/u-bo

Re: What is the right way to run fw_setenv for selecting different ECC or dtb files?

Could anyone please advise how to set up dtb? In running uuu, I can set up "SDP: write -f imx6ulz-kobs.dtb -addr 0x9000", but how can I change to different dtb calling fw_setenv? Thank you and appreciate it. Kind regards, - jh On 5/3/20, Jupiter wrote: > Hi, > >

Issue with 'ubi part' ubi_io_read: error -74 (ECC error)

Sorry for a bit recalcitrant with the issue of calling 'ubi part" error -74 -EBADMSG, is it MTD issue or u-boot issue? I used Linux kernel 4.19 to flash UBIFS volume images ubi.img to imx6ull NAND using following command in Linux: flash_erase /dev/mtd2 0 0 ubiformat /dev/mtd2 -f ubi.img The flas
