No, JLink EDU works just fine for tracing ESP32. I just didn't save my sdkconfig after making changes.
-
Nino admin, just a follow up question, would not having a TRACE license affect J-Link EDU ability to trace using openOCD?
-
I have been going through some ESP32 openOCD documentation (docs.espressif.com/projects/es…api-guides/app_trace.html) and GDB works fine with my J-Link EDU. However, tracing does not. Is this a license limitation on my J-Link or something else? /c Source Code (15 lines)

dope... I reversed some wires, that's what I get for looking at the chip upside down.

Thanks for the tips. I do think that wiring is one of my issues. I have a bus pirate coming in so I'm going to give that a shot, then I will try the JLink again. Chip definitely says Winbond on it. Yes that is the flash (based on pictures from other Asus users), and I'm connecting it with probes from my Saleae in-circuit. JFlash does throw during verification. 3v3 supply verified. So pins 6,8,10,14 are grounded. 3v3 into VTref. When I did not ground the JLink, JFlash reported VTref anywhere from…

So I think I messed up my bios further, which just means that I need to find someone who can provide me with a good dump. I hooked up CS,CLK,DI,DO and provided 3v3 from external source to JLink VTref and to chip VCC. I grounded JLink's CS,CLK,DI,DO GNDs. Odd thing was that when I grounded chip GND the JLink would not detect the chip. So... I left the chip's GND disconnected, which seemed to satisfy JFlash_SPI. The bios was detected not as Winbond W25Q32BV but as: Source Code (2 lines) I then dum…

Thank You!

I got the J-Link EDU 9.4 a while back and have been wanting to learn how to use it but never really had an opportunity. Recently, I bricked my Asus laptop by flashing a bad BIOS. After some research I found a procedure to re-flash the BIOS and would like to use my EDU unit to do so. But since it is an EDU I obviously get the "no valid license found" error. I was wondering if there is a possibility to get a trial license for jflash spi? I have no commercial use for the unit, this is for my learni…
