Question/Issue:
I am using Windows, and I tried to flash the firmware-renesas-ek-ra8d1-freertos.hex that you provided on your site, but neither the .bat script worked nor flashing the hex from the Segger J-Flash platform. However, I can flash another .hex to my board.
Project ID:
If I have misunderstood any part of your instructions, I apologize and am sorry for creating the topic.
I am waiting for your response .
Best Regards.
Hi @Babis
can you paste the error that you get from using the bat and the J-Flash?
Which Jlink version are you using ?
I’m using version V7.92q.
regards,
fv
Hi, @ei_francesco
There weren’t any errors when I ran the .bat; it just showed a cmd window briefly and closed.
Yes, I am using V7.92q. After flashing the .hex, I only see a white screen.
Regards.
If you run the bat from the command line you should see the output, please paste it here.
This is my output:
