Enable to debug RA6M4 using E2 Lite

Hi Kartz,

Our original thought of what the problem is was incorrect.  Could you try using the Renesas Device Partition Manager in e2studio to reset the device to factory default settings?  Then disconnect and re-connect the debug port on the target to power cycle it.  Let us know if that helps with the issue.

Hello Sai

Thanks

I tried using the Renesas Device Partition Manager in e2studio  it show me FAILED! A framing error occurred while receiving data. (BFW: 0354)

i m using 4 wiires SWCLK,SWDIO,3.3V,GND of my R7FA6M4AF3CFB custom board with E2 Lite.

same way i was using with my R7FA6M3AH3CFC custom board. this board working fine.i m able to debug.

But my issue with R7FA6M4AF3CFB mcu based custom board.

Hi Kartz,

Check your custom board MD Pin. If MD Pin se low with pull down that means micro controller in bootloader mode (SCI/USB boot).

So if you want to debug, this MD Pin should be high (INTERNAL FLASH mode).

hi Sai

My MD pin is pulled up.it is ok

is there any thing else in debugger settings?

Kartz,

The RA6M4 is a trust zone part and the debug interface is different from the RA6M3.  Please use the following interface which will allow SWD debugging and Trust Zone IDAU register programming.  This is why the Renesas Partition Manager failed to work.
