Off-Topic Discussion / Re: UART Garbage?
February 10, 2018, 07:41:47 pm
Hello there, got same problem.

Think thats garbage not chinese symbols, my aml8726-mx box hardly software broken.
Thats like firmware got garbage in uart config on board (or suplyer try to secure box). Same problem with non briket box.

Trying to do anything with that box, got 10 box fl200 thin client (Cortex-A9x2x1.5GHz, 1GB, 4GB, Mali400). Got no firmware, factory miss up all my emails. All firmware that i found broken, no usb burning luck, allways errors after write and boot usb_spl.bin with all libusb0 drivers, burning image 1.x and 2.x version same iusse. Uart cable show garbage at Amlogic default settings ( tryed BruteForce baud rate, bits, etc ... no luck ). Compile own openelec image for this aml8726-mx board, try with any boot sd cards no luck, all unbrick methods, 30+ almost same hardware stock firmwares. ( Ember, LibreElec, MXlinux ).

Tryed any aml_autoscript on boot sd. Without UART im blind, but got some garbage UART reports, thats show activity of box when try boot with sd cards with short cut pin 7-8 on chip when plug in power. Got m6 chip (WorldCup device) driver found in host Windows system when short nand chip pin 14-15 when plug usb cable. Stop garbage from UART and start again after i run usb_spl.bin thru update.exe or burning tools. Box got no reset button, swich or pins. Only 4x holes UART connector and 2x holes near ( dont know ??? but not reset ).

So that box hardware, form factor, price very good but software very insecure and week. ( closed sources firmware that store RDP passwords from my privates servers - bad idea. Dont know how many hidden functions got this firmware)

Any ideas ? Solution ?
