Can you please explain how to configure the size of initramfs. My initramfs size is 227 MB

Dear @david.godwin,
Is there any reason for not using sdkmanager for flashing target?

#3

I am using the yocto build as mentioned in the User guide NVIDIA_DRIVE_OS_5.1_Linux_SDK_References and NVIDIA_DRIVE_OS_5.1_Linux_PDK_References
The default build went well and I was able to flash. I have issues when adding my yocto layers and yocto-tegra-initramfs-rootfs.img is more than 200MB. I had a look into all the .cfg files in the bootburn.sh and tried using -k option to specify the cfg file but its all failing. Can you please explain how to configure the size?

Dear @david.godwin ,
I checked with core team on supporting this request.
Seems like you want additional size.

File size = 0x4bed3e0:[E]: nvimagegen : 1025: Error FileOperationFailed (0x12)

Additional Size = 0x4bed3e0 – 0x400000 = 0x47ED3E0 =~75420640 =~ 75 MB
There is not 75 MB available as the total size of the qspi is 64MB.

We would suggest to place their binaries in Ubuntu and run them from there instead of placing them in initramfs
