[meta-freescale] Non-functioning Jethro minimal image for i.MX6 RIoTboard
Hello everyone, I'm new to Yocto and enjoy working with Linux and i.MX6-based devices - and therefore all the more excited to connect with this community! Unfortunately, I'm having some issues getting a minimal image up and running on my RIoTboard using the Jethro branch of the FSL community BSP. I obtain an SD-card image as a result of the build process, however the device does not boot. I executed the following basic steps to generate the image: - Obtained the FSL community BSP and switched to the Jethro branch: $ repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b jethro $ repo sync - Setup the build environment: $ MACHINE=imx6dl-riotboard . ./setup-environment build - Build the core-image-minimal: $ bitbake core-image-minimal All runs fine, with the result being an sdcard.gz archive located in /build/tmp/deploy/images/imx6dl-riotboard. I extract and copy it to an SD card: $ gunzip core-image-minimal-imx6dl-riotboard.sdcard.gz > core-image-minimal-imx6dl-riotboard.sdcard $ sudo dd if=core-image-minimal-imx6dl-riotboard.sdcard of=/dev/sdd However, I am seeing no partitions on the device (e.g. using lsblk). Trying to boot the device with the SD card subsequently shows no output or any reaction.. I find this to be somewhat odd, as I have tried the entire process using the fido branch of the same BSP. I switched to jethro as I plan to integrate another layer which has several patches and fixes incorporated into its jethro branch that are missing in fido (especially things related to the GCC toolchain version...the newer version requires some of the patches applied that are present in the jethro branch of the layer, but not fido). What could the cause of this possibly be, or what could I have missed in this basic setup? Regarding my local.conf and bblayers.conf, I basically stuck to all of the steps in the following tutorial, except that I did not add a custom layer but went right to building core-image-minimal and used the jethro branch instead of fido: https://community.nxp.com/docs/DOC-103530 I'd appreciate it if someone could provide me with some insight as to what could be going wrong here!

Re: [meta-freescale] Non-functioning Jethro minimal image for i.MX6 RIoTboard
Hi Chris, Thanks for sharing this. If the image is completely broken, then there are 3 possibilities that easily come to my mind: 1. broken image_types_fsl.bbclass (this is where the sdcard image is generated) 2. broken image variables 3. broken bootloader (highly unlikely) I haven't touched/tested the riotboard build for months, so I have lots of things to catch-up. I'm now building jethro & krogoth to see what's going on there. In the meantime, patches are always welcome!

Re: [meta-freescale] Non-functioning Jethro minimal image for i.MX6 RIoTboard
Chris, In jethro the sdcard.gz is impossibly small (24 KiB). For comparison a compressed sdcard image from fido is ~8 MiB (and fido sdcard image boots fine). Regards, Nikolay -- ___ meta-freescale mailing list meta-freescale@yoctoproject.org https://lists.yoctoproject.org/listinfo/meta-freescale
Re: [meta-freescale] Non-functioning Jethro minimal image for i.MX6 RIoTboard
Chris, Can you please try adding the following to your imx6dl-riotboard.conf: SOC_FAMILY = "mx6:mx6dl" ...as it worked fine for me. It looks like SOC_FAMILY was empty and SDCARD_GENERATION_COMMAND_mx6 is not invoked. We need to check with Otavio why this line was removed, as I'm sure he had a good reason for this change. Kind regards, Nikolay -- ___ meta-freescale mailing list meta-freescale@yoctoproject.org https://lists.yoctoproject.org/listinfo/meta-freescale

It is the same meta-fsl-arm-extra renamed. Please find more information at: https://www.mail-archive.com/meta-freescale@yoctoproject.org/msg19181.html -- Otavio Salvador O.S.
