Qoriq LS1046ARDB Yocto SDK wic image

[pholden]

I got an image for LS1046ARDB finally built for the LS Qoriq Yocto SDK, I am working with branch "styhead".  Now I want to make it bootable by SD card.  I have two questions:

1.  u-boot.  Where is the sdcard defconfig for LS1046ARDB?  I've changed "UBOOT_CONFIG" to add 'sdcard', but there is no corresponding defconfig to go with it.

2.  wic image.  How do I configure LS1046ARDB to generate a wic image I can dd to the SD card?  I tried adding "IMAGE_FSTYPES = "wic" to my local.conf, but bitbake no longer works.

So far I've figured out the "wic" part of my question. 

I'm still wondering where the SDCARD u-boot defconfig is for the LS1046ARDB.  Using the tfa defconfig is definitely not working for SDCARD image.

Hello,

To select SD card as the bootable source it is selected by the RCW, when you perform bitbake qoriq-composite-firmware you will build the image of the firmware (RCW/PBL, ATF, Bootloader (U-Boot or UEFI), secure headers, Ethernet MAC/PHY firmware, dtb, kernel and tiny initrd RFS). The composite firmware can be programmed at offset 0x0 in flash device or at offset block# 8 in SD/eMMC card. 

bitbake qoriq-composite-firmware will create 3 options:

firmware_ls1046ardb_uboot_nandboot.img
firmware_ls1046ardb_uboot_norboot.img
firmware_ls1046ardb_uboot_sdboot.img

select the sdboot option.

Thanks, I ran bitbake and used "dd" to push the sdboot file to the SD card at offset block 8.  I now have the following when I run sd_bootcmd:

bootargs is still pointing to /dev/ram0:

So it's not at all trying to boot from microSD.  I checked the switches (as defined in user guide for LS1046ARDB) and they look fine.

Hello, 

You don't have to modify bootargs, or any other configuration. 

Please follow the LLDPUG with an official branch like Mickledore, the built images are configured for SDcard options, no more configurations needed and the firmware should give you something like 10 seconds to stop in U-boot.

https://www.nxp.com/docs/en/user-guide/UG10081_LLDP_6.1.55_2.2.0.pdf

After you install the machine requirements you can also use as reference the link below to build the images.

https://github.com/nxp-imx/meta-nxp-desktop/blob/lf-6.1.55-2.2.0-mickledore/README.md

Also make sure you are using the correct version of flex-installer, in this case flex-installer_1.14.2110.lf to deploy the Layerscape LDP images in the SD card.

Thanks for the update, I'll try this out next.  Right now, I am just using TFTP/Ext2Load because I had to start making progress on the driver and user app I'm working on for my client.  But I will definitely try your suggestion and  let you know how I make out.

Thanks again!
