Sdkmanager version should not be the problem if you really understand how the flash work is done here…
Sdkm uses the driver BSP to do the installation… and this BSP won’t change when sdkm is upgrading…
For example, the “jetpack4.5.1” in sdkm 1.4.x is still the same one even when it is sdkm 1.6.x. Actually, I never really try to memorize the sdkmanager version… because there is no need to remember such number…
