Raspberry Pi 3B+ v1.4 Setup Process

[beauchab]

After downloading image and flashed using balena etcher created typical boot response: 4 long blinks followed by 7 short
Added boot mod described below, system worked properly but did not recieve input from the hifiberry for audio input.
In order to fix the audio issue the .asoundrc file at <~/.asoundrc> needs to be modified as follows:

pcm.!default {
type hw
card sndrpihifiberry
}
ctl.!default {
type hw
card sndrpihifiberry
}

The system was then rebooted and audio input worked properly.

Boot modification:
Flash second sd card with Raspberry Pi imager - choose Raspberry Pi OS (Legacy, 32-bit) which is Debian Bullseye
Boot this sd card on the Raspberry Pi 3B+ 1.4 and ensure that you launch the desktop
After desktop boots shut the pi down.
You will need the ability to mount two sd cards to a system for this next step,
I am using a sandisk
Mount the bullseye image and the desired vserpi image to your system and copy the following files from the bullseye images /boot/ directory:

.firmware_revision
bootcode.bin
fixup.dat
fixup_cd.dat
fixup_db.dat
fixup_x.dat
LICENSE.broadcom
start.elf
start_cd.elf
start_db.elf
start_x.elf

Copy these files to a separate folder in a known location on your system as they will be useful in getting all vserpi systems running on a raspberry pi 3b+ 1.4
Open the /boot/ directory of the vserpi image, and copy all of the files within the Boot_Files directory to the /boot/ directory of the vserpi image and click 'yes' to overwriting their reciprocal files in the vserpi image.
After replacing these files, safely remove the sd card, plug it into the vserpi system with all peripherals, then power the system on.
It should boot properly to the vserpi synth.
