Canon SX510IS does not work on a memory card with two partitions.

Hello.
There's a Canon camera SX510IS
I make a map for it with two partition, bootable with DISKBOOT.BIN and PS.FI2 files
And the second partition under the photos.
No matter how I create the second partition, the camera does not see it.
During loading shows CHDK logo and writes "missing files"
I create partition using SDM Installer
The memory card is used by Samsung 64Gb
If you make one partition of the FAT12 on this memory card, then the camera is loaded from it and successfully photographs on this partition. But 4Gb very little.
Similarly, I prepare the same memory card for Canon A490 with two partition, works.
Is this a problem with CHDK for camera SX510IS?
Can this be corrected?

SX510 supports booting from FAT32 (as do all powershots released 2011 and later), so there's no need for multiple partitions. On windows, you may need a 3rd party application to format the card FAT32 rather than exFAT.

Don't forget what the H stands for.

That's what happened.

Created one partition.
Formatted under the FAT32
Made the section "Active"
The camera doesn't load from it.
If Flash Card Write Protection is enabled, the camera writes "Write Protected Card"
If the security is disabled, nothing happens.
What am I wrong about? What am I doing wrong?
