Advanced users • Re: TRYBOOT_A_B not booting into secondary boot partition with reboot '0 tryboot'

I modified a RaspiOS Bullseye Image on my 16GB SD-Card. It has 2 partitions.

• part#1: 256MB primary FAT boot partition (bootable)

• part#2: ~10GB primary partition with Root Files System

Then I split part#1 into 3 partitions by using fdisk:

• part#1: 2MB primary FAT partition for autoboot.txt

• part#3: 126MB primary FAT boot_a partition (bootable)

• part#4: 126MB primary FAT boot_b partition (bootable)

• part#2: ~10GB primary partition with Root Files System

Tryboot_A_B works!

Then I wanted to add another 5th 4.5G extended + logical FAT32 partition for user data and logging. fdisk refused to do that since 4 primary partition were in use. It seems RaspiOS Bullseye Image uses primary partition for the Rootfile system and I added 3 additional for TRYBOOT_A_B. I hit the maximum.

How to solve that issue to add an additional extended partition?
Do I have to add an extended partion and then a logical for 10GB rootfs and 4.5GB for user data?
Any suggestion on that?

Thanks in advance
