Yocto browser require low memory footprints
#yocto
#meta-freescale
yogeshbsa89@...
Hi ,
We are using Yocto Linux 3.0 zeus branch on imx6 based SOC. we are looking for light weight web browser since our HW platform has only 1 GB of RAM supports. as of now we are using chromium version 75. but in some use cases we are short falling of RAM. sometimes we have also seen chromium triggers OOM which crashes our main application. please suggest some light weight browser options or any idea with which we can reduce memory requirement of chromium. our use case of browser is to only send some predefined screens to one of the browser tab.

imx51evk and u-boot

Hi all.
I'm trying to build Yocto dunfell for imx51evk derived board. The board has only sd card with 1 dram of ram. It is better u-boot-imx or u-boot-fslc as bootloader? I try the two version of u-boot but I get only the presentation of uboot. Uboot is not able to boot MZ

signing an initramfs kernel
Embedded 1
On my i.mx8mp board I have secure boot enabled. I can boot a signed kernel fine. I'd like to now sign the kernel used with the initramfs image. I don't understand if that kernel is the same as the regular kernel and if I can just replace the signed kernel with it?
when I build my initramfs image recipe I get a few new files including a rootfs.cpio.gz file and a Image-initramfs file. I'm unclear what the differences are between these files. If I unpack the cpio.gz file I see an Image file in /boot/Image. I don't seem to be able to boot this cpio.gz image though.
