Hi all,
I have 2 pogoplug pro. One of them is running pi-hole 5.x for quite some time now. This works perfectly without any downtime or crashes.
Looking forward to the future, I wanted to give Beta 6.0 a try to see what to expect from this upgrade. So I created a fresh Debian (bookworm) install on another pogoplug pro (identical chipset / architecture).
neofetch shows this:

Using the instructions I can find here: Pi-hole V6 Beta Testing – Pi-hole I tried to install Beta 6.0. In one of the final steps, the script tries to download a binary and fails, because this architecture seems unsupported. So I downloaded an ARM v6 binary here: index - powered by h5ai v0.30.0 (https://larsjung.de/h5ai/), pihole-FTL-armv6.
This one fails with an Illegal instruction exception. Below you can find the strace:
strace ./pihole-FTL-armv6
execve("./pihole-FTL-armv6", ["./pihole-FTL-armv6"], 0xbec53d70 /* 17 vars */) = 0

brk(NULL) = 0x16bf000
brk(0x16c1000) = 0x16c1000
mmap2(0x16bf000, 4096, PROT_NONE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x16bf000
--- SIGILL {si_signo=SIGILL, si_code=ILL_ILLOPC, si_addr=0x3f2e78} ---
+++ killed by SIGILL +++
Illegal instruction
Finally I tried to compile the binary myself, using the instructions I can find here: docs/docs/ftldns/compile.md at release/v6.0 · pi-hole/docs · GitHub
This also seems to fail

So, TL;DR, two questions:
- will armv6l be a supported architecture?
- anything I can do to fix the build and compile the FTL binary myself?
Many thanks in advance, and thank you for delivering such a nice product 
It has a limited amount of memory (128MB), so building the binary is a real struggle
