Hi all,
First of all, forgive me for not being an electronics engineer - however I hope you'll be able to help me. A couple of years ago I had a company design a pcb for a project of mine. I had the possibility to change some of the settings by hooking it up to a secondary board which connects to my pc and sending simple text commands. I cuold for example read the settings by sending the command 'paraget' en changing a setting by sending 'paraset 1 5' which changed the first setting to value 5.
All worked fine until the secondary board got lost during a move, and the company who designed the board no longer exists. Now I'm trying my best to find the right components, and I feel that I'm almost there but not quite yet.
So, here's what I have to work with:
- I have on my board an 8 pin 'debug connector', where I mapped the pins to the processor pins (the processor is a 64 pin XMC4400 F64F256 AB (https://www.infineon.com/dgdl/Infineon-XMC4400-DS-v01_03-EN.pdf?fileId=5546d462696dbf12016981795855391d)
I managed to find the following connections:
- VDDP
- P1.5
- Not Connected
- Not Connected
- PORST
- VSS0/VSS
- TCK
- TMS
- When I power the board, there is 3,3V between VVDP (+) and VSS (-) and between PORST (+) and VSS (-)
- I imagined I could use the Analog Devices ADALM-UARTJTAG board to communicate with my board, but I think the pin layouts are not the same. From the datasheet I found:
I think I should rewire the cable between the 2 boards, but other than connecting TMS to TMS and TCK to TCK I am lost at how to correctly wire the rest.
Thanks for the help!
