Re: Raspberry Pi 4 (2GB) Solid green and red lights and no boot

Unfortunately i don't have access to another Pi now (specially not a PI4 that appears to be needed for this task) The code is Python 2 so it should run on anything which supports Python 2, Pi or PC. Not having a Pi 4B I don't know if I have the latest 'pieeprom.bin' so I would have to investigate t...

Re: Raspberry Pi4 bootloader update package

Just to note that '/usr/bin/rpi-eeprom-config' is Python 2 specific so it may be wise to update that for Python 3 before Python 2 goes 'end of life' at the end of the year - pi@Pi3B:/tmp $ python2 /usr/bin/rpi-eeprom-config pieeprom.bin BOOT_UART=0 WAKE_ON_GPIO=0 pi@Pi3B:/tmp $ python3 /usr/bin/rpi-...

but they mention that i have to put the option BOOT_UART=1 but it couldn't find where i have to set this config. It's not clear is it. From the following it reads to me that you need to have a working Pi with rpi-eeprom installed and a copy of 'pieeprom.bin', need to extract its current configurati...

Re: USB Blown is there any USB output on GP10.

I have only had my Pi 3B+ for just over a month so its too soon to scrap. Any ideas. 'Suck it up' and buy a replacement Pi. Take it as a lesson learned the hard way. I would probably remove the USB current limit chip, solder 5V to the USB Vbus pins and see what happens. If not you seem to have fata...

Re: 'buster': apt-get update > no new updates for days...

It's possible. There was an upgrade for 'rpi-chromium-mods' around the 15th, some others around the 10th, including 'systemd' which I would have expected everyone to get. So a lite install may not have seen an upgrade for a week. You can check your apt / apt-get history with - cat /var/log/apt/histo...

Re: trying to buy more than 1 pi zero

Interestingly, you can go to any Micro Center in the States and buy as many Pi Zero computers as you need at a time with increased per-unit pricing. That's the most bizarre pricing I have seen, for a Pi Zero W - 1 at $5.00 each 2-5 at $14.99 each 6+ at $19.99 each https://www.microcenter.com/produc...

Re: RPi3 not booting after amplifier was wrongly connected

Electronics really don't like reversed voltages so I would imagine you have created a domino-like cascade of failures.

The power LED may come on but everything else is likely dead or damaged, at least enough to prevent it booting.
