Re: Need LA-E541P io kbc pin connection
What model is your programmer, is it a vertyanov clone, is pin 1 of the keyboard connector on the left or right side,are the pins up or downLast edited by SMDFlea; 12-23-2021, 08:07 AM.Comment

Re: Need LA-E541P io kbc pin connection
Check which pin has +5VALW in the 2nd picture at post #2 then you will know if pin 1 matches with both connectors or if its reversed. I can`t help you with the software if some settings are different to the genuine vertyanov .Attached FilesLast edited by SMDFlea; 12-23-2021, 10:34 AM.Comment

Re: Need LA-E541P io kbc pin connection
LA-E541P
NPCE388NA1DX
***********************************
Tried this combination of code:
(with 30 pin, one side)
LA-E541P KB_pins=32 LEFT 08MM JENK=39 TCK=51 TMS=52 TDI=53 TDO=44
But it says:
"Invalid settings for Nuvoton MB!"
(with Read and Write buttons inactive)
But when I push "Check connection" it is likely has a connection with MB:
(No any error msg)
"FTDI driver version 21236
Version FW JIG M328_EPM240_v34
2F2F7B916B2DBDF165C3C665"
************************************************************
With the given configuration, for example:
LA-E451P (JKB1) KB_pins=32 LEFT 08MM JENK=20 TCK=8 TMS=7 TDI=6 TDO=17
as you offered above, it gives error:
(after connection check)
4/12/2023 4:23:19 PM
FTDI driver version 21236
Version FW JIG M328_EPM240_v34
2F2F7B91632DBDF165C3C665
Read NUVOTON ID FFFFFFFF
Wrong ID. Break.
+++++++++++++++++++++++++++++++++
Possible reasons:
1 No power is connected to the MB
2 No power on a chip EC
3 Defective chip EC
4 Invalid defined first contact
5 Invalid settings for MB

How to make active Read and Write buttons with non standart configuration, please advice!Comment

I have a drill and battery but no charger so I bought a "universal charger" 120ac in ... 12vdc out (not really universal in lithium world). Anyway it has three contacts, positive, negative and "T" (temperature sensor). I connected those contacts to the contacts on the battery. No charging happened and only the status light is on (green solid) which the label indicates "100% charged".... but the battery isn't near that at around 9v and dying. There doesn't appear to be any difference whether the battery is connected or not. I got suspicious and pulled the... -
Hi everyone, I hope someone can help me solve my problem, I have the case of a legion t5 where I have installed an asus tuf gamig a520m-plus motherboard, the audio connection cable on the case is an F_audio connector with 14 PIN , on my new motherboard the connector is a 10-pin AAFP, I saw that there are adapters on sale but at the moment I have no way of having them available in a short time, I made several attempts and managed to listen from the front headphones, only that there are some problems, the headphones are only detected if the microphone is connected, I definitely got confused with... -
Greetings and Salutations!
I have encountered a faulty GPU — an Inno3D RTX 2070 Twin. There was a shorted MOSFET on the Vcore rail.
The faulty DrMOS was removed, and the burned PCB area was milled away.
All voltages are now good, but the GPU is not being detected.
I found that the CS pin of the BIOS (GPU) is not being pulled low, and thus, the GPU isn't detected.
I wanted to measure the SM_Data and SM_Clock, but to my surprise, there is no connection at all.
I thought these pins were used for communication during startup?!?

could someone please upload a unlocked npce388 EC file?
thanks in advance

This particular unit powers up, LEDs behave normally, but broadcasts no SSID, will not mesh with any other routers. Plugging in an ethernet cable from a Windows laptop results in "unidentified network" with an autoconfigured IP address and no response to pinging 192.168.1.1.
I was able to log into serial/UART by connecting the 6-pin header to the GPIO on a Raspberry Pi Zero W (GND to GND, TxD to RxD, RxD to TxD, no connection between +3.3V as it is supplied on both sides) using Minicom, command:
...Code:sudo minicom --baudrate 115200 --device /dev/ttyS0
