Vu+ Uno 4K UART pinouti skeem

[Põder]

Lasin oma lollusest flashi tühjaks, seega USB-lt bootimine enam ei toimi.
USB–TTL konverter on olemas, aga ei tea täpselt, kus asuvad Uno 4K emaplaadil RX, TX ja GND pinid.

Kas keegi saaks jagada skeemi?

kas üldse enam lootust kui tegin, flash_eraseall /dev/mtd0

See RJ12-kujuline pesa, mille all on kiri IR SENSOR / RS-232, tekitab palju segadust:
Mõnel vanemal Vu+ mudelil oli seal päris RS-232 (±12 V signaalidega), mida sai kasutada .nfi flashimiseks.
Uno 4K puhul see pesa EI OLE klassikaline RS-232, vaid pigem IR sensor / laiendus. Box ei väljasta sealt standardset serialit, mida saad otse PC COM-pordiga kasutada.
Uno 4K puhul töötab ainult emaplaadi sisemine UART päis (3.3 V TTL)

Vähemalt AI kirjutas nii

Pigem ootab ees emaplaadi vahetus või uus box.

To undo a multiboot, search for "BPanther's Image".

I finally got it working with a similar error pattern, using "flash orgies." First, I tried the latest original VU image, then started with the oldest original VU image. I did this with and without "mkpart.update." However, I was sure the box in question wasn't multibooting. At some point, the menu button responded. I can't remember whether the installation wizard appeared beforehand. I then tested the box with the original VU image and then, after a few days, flashed the latest VTI image. The box does what it's supposed to do. However, it's entirely possible that there are defective clusters in the flash memory.
I have a Mipsel box; I have no idea if it will work for you with your ARM box.

USB-lt siis jutule ei võta?Kui võtab lase usb-ga uus bootloader peale seejärel originaalimage otsa
