Ok, looking at your photo it looks like R75 is going to pin-19 (or close to it) on the MCU, it impossible for me to tell though based purely on the image your provided, if this is the case then UART/terminal is obviously not going to work.
On my board R75 goes to pin-23 of MCU (check my img)
Well, i analized your pic in my PCB, and Connections of resistors are the same like R60 connect to pin 37 pin, R75 also connect to pin 23,
Also, don't use a 30ohm resistor - use a 0-ohm resistor, a 1-ohm resistor or just jump with a wire. although 30-ohm is pretty low and probably absolutely fine to use, it's best to rule this difference out.
Ok i will try. So i trying solder R75 0ohm and also terminal not respond.
Put your multimeter in continuity mode, put one probe on pin 23 (based on my img) and find and confirm which pad it's going to. do the same with pin 37 on the MCU (again based on my image) although again looking at the image this time R60 does in fact look like it's hooked up the same as my board.
Connection pins are the same with my PCB.
What is your end goal here? are you just experimenting? like i said in my previous post, i was not able to find a solution so.....
well i trying to run my PCB in internal ROM, because in external ROM my PCb not work thats all
Also, are you working with the board uninstalled/not connected to the motor etc? in my case everything was installed as normal.
differently, first uninstalled , not connected to motor, second installed with disk.
Also please give me details on your UART adapter, and rule out that that is indeed working as it should by doing a Tx/Rx loop test in terminal - you also might want to rule out a software issue and try realterm and/or hyperterminal.
My Terminals are homemade building
First terminal are build in MAX232 TTL converter it is standard application 3,3Vio
Second terminal are also bulding on PL2303HX TTL USB TO TTL CONVERTER 2,5Vio, and also standard application.
