Could you please explain why we need to erase and flash bootloader again? Could you elaborate the reason behind this step?

Hey @Igor, is there new bootloader firmware built as a result of your changes? I can probably do a quick test at some point (I've got a large build underway on one of my devices). This page is probably in need of work: https://www.armbian.com/espressobin/ the download links don't seem to work for me (they redirect to mirrors.aliyun.com)

hello everyone!! I have the same box here, it's says that it's 8gb 128gb, but real specs is 1gb of ram and 8gb of rom, any help? Thanks!

Please help, I'm stucked (or, may be stupid). I use my tv-box as printserver (Klipper), it works fine. Now I attempt to use accelerometer ADXL345 usb board, and I havnt success. It must be simple task, but something went wrong here. Board works, flashed normally without any errors and shown as should by lsusb: klipper@transpeed-8k618-t:/usr/lib/udev/rules.d$ lsusb Bus 003 Device 002: ID 1a86:7523 QinHeng Electronics CH340 serial converter Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 013: ID 1d50:614e OpenMoko, Inc. rp2040 Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Also, it must be appear as serial device, but... klipper@transpeed-8k618-t:/usr/lib/udev/rules.d$ ls -l /dev/serial/by-id total 0 lrwxrwxrwx 1 root root 13 Nov 8 18:47 usb-1a86_USB_Serial-if00-port0 -> ../../ttyUSB0 ...here is my "Ender" only. dmesg: [30617.149526] usb 4-1: new full-speed USB device number 22 using ohci-platform [30617.358206] usb 4-1: New USB device found, idVendor=1d50, idProduct=6177, bcdDevice= 1.00 [30617.358227] usb 4-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [30617.358235] usb 4-1: Product: rp2040 [30617.358242] usb 4-1: Manufacturer: katapult [30617.358249] usb 4-1: SerialNumber: E6647C7403433637 [30663.467079] usb 3-1: new full-speed USB device number 3 using ohci-platform [30663.665820] usb 3-1: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice= 2.64 [30663.665867] usb 3-1: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [30663.665891] usb 3-1: Product: USB Serial [30663.668223] ch341 3-1:1.0: ch341-uart converter detected [30663.680198] usb 3-1: ch341-uart converter now attached to ttyUSB0 I've search solutions, but have not resolve.
