Depends on your board design. Why dont you upload some high-res photos of the PCB?tx can have 3volt... and how many kohm ?

Hi i have locked uart... How to unlock uart ?Depends on your board design. Why dont you upload some high-res photos of the PCB?
I do no know where TX pin But C1 to C4 can uart open port?You find the TX pin in the board??
You get log loder ?
if u have logic analyzer or DSO u can easy find the pin rx or tx but the if the rx disabel by loder that hard to find .Search in Google find uart tx rx many tutorial
How do you access your rx tx gnd and 3.3v pin? Is that from C1 to C4 jumper?Hi someone have custom firmware for NANDFLASH MXICIS U4 for uart unlock?
U15 is a RAM not a NAND flash, so you only have two NAND flash which is U4 and U14Someone say Custom firmware on Nand flash then will uart port open!?
but which Nand flash? I have 3 Nand flash?
U4, U14 and U15...
I do no know but I have CH4 CHannel 4? Is uart but locked…How do you access your rx tx gnd and 3.3v pin? Is that from C1 to C4 jumper?
C1 is 0 volt and C2,C3 and C4 is 6 volt but it’s not uart I think maybe?How do you access your rx tx gnd and 3.3v pin? Is that from C1 to C4 jumper?
Definitely notC1 is 0 volt and C2,C3 and C4 is 6 volt but it’s not uart I think maybe?
What baud rate did you use?I do no know but I have CH4 CHannel 4? Is uart but locked…
Speed is buad? I think Speed was 9600... But my usb to uart cable not work more i think is Broken after connect uart. :/ because I think locked uart thats why...What baud rate did you use?
Yes Baud Rate is a speed. If your USB to UART cable doesn’t work after the first connection, it did not mean that UART is locked. It actually meant that you did not connect UART pinout correctly, and that incorrect connection broke your USB to UART cable, for example, you might connect 3.3V pin to GND pin. The only solution now is to get a new USB to UART cable and double check RX TX and GND pin.Speed is buad? I think Speed was 9600...
