Dual boards now included...

Once I start getting some confirmations that this works for more people than just me, I'll make it part of the boot process :)

Keep testing for me, I need to run mine for longer too and see if it stays working or if the modem locks up/resets again.
After a reboot it will go back to not working (currently) but once we have it sorted - it should stay put.

Since my last post it's been running like a champ. Modem is nice and steady. Haven't had to re-reset it again.

Update and then Upgrade to 4.1.0-RC4 and this is now in the boot process, it ONLY takes effect on Pi 4 hardware at boot time.

Currently this cures VR2VYE Dual / HS_HAT Simplex and HS_HAT Duplex boards, and Zumspot Simplex.
If anyone runs into other boards that boot up stuck in reset/bootloader let me know pls.

Mine is a China spot duplex and uses the MMDVM_HS_DUAL HAT (DB9MAT, DF2ET & DO7EN) for Pi (GPIO) modem selection.

It was working fine after the last restart I posted. Now it's been updated and hasn't had an issue since.

Oh, and since I ordered another duplex board thinking I had a bad one, I now have a spare duplex on a 3b+. So Win Win... hehe
