Jetpack 4.3 APP partition starts at new address 4104


What I see is that in Jetpack 4.2 - L4T 32.2.1 (and older ones), first partition APP starts at address 4097:

Device Start End Sectors Size Type Name
/dev/mmcblk0p1 4097 58724352 58720256 28G Microsoft bas APP
/dev/mmcblk0p2 58724353 58732544 8192 4M Microsoft bas mts-bootpack

In Jetpack 4.3 - L4t 32.3.1, first partition starts 8 blocks further, it starts at address 4104:

Device Start End Sectors Size Type Name
/dev/mmcblk0p1 4104 58724359 58720256 28G Microsoft ba APP
/dev/mmcblk0p2 58724360 58732551 8192 4M Microsoft ba mts-bootpack

Do you have any idea if those 8 blocks matters or not?
Can we keep our first partition where it is now? at address 4097?


Jetpack4.3 has some partition update. Please refer to L4T development guide and check the latest partition layout.

Hi WayneWWW,

Thanks for your reply.
L4T development guide doesn’t include TX2 P3310, but I suppose it has the same partition layout as TX2i P3489 because of same family.

So you confirm that partition APP has changed its starting address?


Yes, TX2 and TX2i are same family so the partition table is the same.
