Hi Forum members,
Currently I am using RA6M3 board and using e2lite debugger as shown below.
Was using this to download and debug.
Unfortunately it stopped working and I have no clue on how to proceed (new one seems quite costly).
While browsing, I came across FT232H chipset which mimics USB to JTAG connectivity. Any of you have used this FTDI chipset for JTAG debug? Your feedback would help me to resume my debug .
Hello MANJUYADAV,
Thanks for reaching out Renesas Community!
First of all, there is a self-checking Program, in order to verify the e2lite debugger's state, you can download it from here:
https://www.renesas.com/us/en/document/swo/e2-lite-self-checking-program-v10000?r=488806
Ιf the result is fail, you can't use the e2lite debugger anymore.
Also, do you use any evaluation kit of Renesas or your customized board with the RA mcu integrated in it?

Hi AL_Renensa,
Thanks a lot for your suggestion. I quickly tried this and below is the message I am getting.
I have developed a customized board with debugger connection to use this debugger. But as current debugger is not working, I desperately trying to see if I can use FT232H.
Please let me know if you have any suggestions for me.
According to the EK-RA6M3 user's manual, there are three different ways for debugging. ( Chapter 5.2 Debug and Trace):
https://www.renesas.com/us/en/document/mat/ek-ra6m3-v1-users-manual?r=1168086
Τhe first and the third method uses S124 Synergy Debug mcu to debug the target RA mcu, so they cannot service n your case.
The second way (Debug in) describes how to use one 20-pin connector or one 10-pin debug connector based on SWD or JTAG interfaces. For example, e2lite debugger uses these connectors, in order to debug your mcu.
Find attached the e2lite debugger documentation that shows these connections:
https://www.renesas.com/us/en/document/mat/e2-emulator-e2-emulator-lite-additional-document-users-manual-notes-connection-ra-devices
FT232H covers the JTAG interface, but there isn't any official documentation, which describes how to debug using FTDI chipset.
