![]() ![]() To apply a different device tree, must I re-use the flash.sh with the according option? Or is it enough to have the FTD entry in nf to point to the modified dtb? Wrapping it up, the question is: am I going into the right direction for searching the issue? Am I missing a stupid flag somewhere? common/tegra194-p3668-common.dtsi /home/saldegheri/jetson/Linux_for_Tegra/sources/hardware/nvidia/platform/t19x/jakku/kernel-dts/common/tegra194-p3668-common.dtsi > #include "tegra194-camera-jakku-rbpcv2-imx219.dtsi"ĭiff -r. ![]() #include "tegra194-camera-jakku-rbpcv3-imx477.dtsi" common: tegra194-camera-rbpcv2-imx219-auvidea.dtsiĭiff -r. common: tegra194-camera-jakku-rbpcv2-imx219-auvidea.dtsi I then exported such GPIO using this commandĬhanging the “value” of such pin, seems to disable the recognition of the SD card: no error thrown, but no device appearing in lsblkįollowing some more thread I found in the forum, I tried to edit the dtb file in the /boot/dtb directory using this commandĭtb -I dtb -O dts -o kernel_tegra194-p3668-0001-p3509-0000.dts kernel_tegra194-p3668-0001-p3509-0000.dtbīut the source is not neat as the one in the forum, which I finally located in the kernel source under hardware/nvidia/platform/t19x/jakku/kernel-dts/. Needs device tree changes to be activated which includes enabling socket pin 211.įollowing that, I tried to export the socket pin 211 which, as far as I understood from their docs, is mapped to GPIO3_PS.04, but I didn’t understand if this choice is specifically made because of the carrier or if it is the mapping NVIDIA provides. There is one manual process which is not explained in details that says To install it, I applied some binaries upon the downloaded Jetpack as per their instructions, so the system is slightly different than one within a devkit. mmc1: error -110 whilst initialising SD card ![]() The error I am experiencing is that, when I insert the SD card I get this statement # dmesg | tail -n 1 So, about the system $ cat /etc/nv_tegra_release I saw there is the “contact the vendor” policy (which I already did, waiting for the response), but I would hope to get pointed towards the correct direction so I learn a bit more about the inner working on the Jetson world (or more precisely, the embedded linux). I am trying to enable the usage of SD card in the system using a Jetson Xavier NX 16 GB module and the Auvidea JNX30D as the carrier. ![]()
