Access QSPI & eMMC uboot env variables in linux userspace LS1046ARDB

[sheikfaaruk]

I am working with Custom-LS1046ARDB Evaluation Board to develop a network based application. I have started my project with Flex-builder(flexbuild_lsdk2108), Flex-installer(version: 1.13.2108) and Codewarrior IDE.

I have download the images from https://lsdk.github.io/components.html

boot_LS -> wget https://www.nxp.com/lgfiles/sdk/lsdk2108/boot_LS_arm64_lts_5.10.tgz

firmware image -> wget https://www.nxp.com/lgfiles/sdk/lsdk2108/firmware_ls1046ardb_sdboot.img

Rootfs -> wget https://www.nxp.com/lgfiles/sdk/lsdk2108/rootfs_lsdk2108_ubuntu_main_arm64.tgz

I have depolyed the image's in SD card through flex-installer:

$ flex-installer -i pf -d /dev/sdx (partition and format the target storage device)

$ sudo flex-installer -b boot_LS_arm64_lts_5.10.tgz -r rootfs_lsdk2108_ubuntu_main_arm64.tgz -f firmware_ls1046ardb_sdboot.img -d /dev/sdx

I already posted question about "Access U-boot env variables in LS1046ARDB Linux user space " for SD card in NXP Community and also get a solution from NXP TechSupport

I have questions about fw_env in LS1046ARDB :

1. Previously i booted uboot through SD card so ENV_ CONFIG_ENV_SIZE=0x2000 CONFIG_ENV_OFFSET=0x500000 used for reading/writing uboot envirnoment variables in the linux userspace. Can you guide us to know about the CONFIG_ENV_SIZE, CONFIG_ENV_OFFSET values for uboot environment in QSPI and eMMC blocks.

And Also I have question :

In LS1046ARDB Evaluation Board have 16GB-RAM

setenv othbootargs default_hugepagesz=1024m hugepagesz=1024m hugepages=4 isolcpus=1-3 bportals=s0 qportals=s0 iommu.passthrough=1

In Custom-LS1046ARDB Board have 4GB-RAM

setenv othbootargs default_hugepagesz=1024m hugepagesz=1024m hugepages=2 isolcpus=1-3 bportals=s0 qportals=s0 iommu.passthrough=1

I'm using hugepage for running DPDK application, is hugepages=2 is enough because lsdkug_2108 doc mentioned hugepages=4 by default.

According to configs/ls1046ardb_tfa_defconfig, the parameters are still as the following.

CONFIG_ENV_SIZE=0x2000
CONFIG_ENV_OFFSET=0x500000

DPDK can work normally with hugepages=2 .
