Hi
I have a J-link and i am trying to read data from chip but keep getting an error
I am trying to program a new file to the internal flash of the chip below
TMPM361F10FG

The chip is on an HDMI board from an onkyo avr
Below is the service manual
https://www.manualslib.com/manual/1027090/Onkyo-Tx-Nr616.html

failed to connect, could not establish a connection to target

Attached is screenshot of error from J-flash


I have tried shorting my cables
I have tried applying power direct to the board externally from 3.3v output from j-link

Is it because it is too less amps

Do I need to keep the board inside the chassis and then connect using J-link

Has anyone seen such error before, if so how did you fix it, please

Thanks so much in advance

Welcome to AAC!

Are you sure that the ROM read protection has not been enabled which would prevent you from reading the chip?

Next step would be to make sure that the Segger J-Link suports the TMPM361F10FG chip.
Is there a menu on the J-Link app that allows you to select this MCU?
Does the Onkyo AVR connector match the J-Link connection?
Check the TMPM361F10FG manual.

Hi mate
I have checked and J-link supports the chip
Also the service manual states that J-link can be used to debug this

So I have not connected the J-link to the board while connected in the chassis
I have the board outside and powering it externally
I have 3.3v connected to the positive side of C8708
I am using the 3.3v output from My J-link
Do you know how many amps would be enough for this to work
I have read that it could be the wire length that can cause problems like this but even if the wires are a little long it should still connect right ?
I am really banging my head on how to get this fixed
I will really appreciated the help from this amazing forum
