[OpenOCD-devel] PowerPC / OSBDM target questions

2015-05-04 Thread James Murray
upport it. Not sure how to tell gdb that it does. 6. Is there a way to "hot-sync" with a running target? 7. What's needed to let gdb or Eclipse "know" what regions of memory need hardware breakpoints? I'm sure I'll have other questions as my work proceeds, but th

Antoine, The work I did wasn't finished enough to release it, but it did work (just about) well enough that I was able to use it myself. I updated it to the current version of OpenOCD and could send you a patch if you want? I was able to find enough information to figure out how the JTAG/OnCE int

I've created a "diff -u" of my changes against a pull from git on 2017- 09-25. http://www.jamesmurrayengineering.co.uk/files/openocd-mpc5xxx-jsm-20170 927.diff.zip Hopefully that is clean enough, without too much cruft and does include all needed files. Recent comments seem to be suggesting that

I had been using OpenOCD with an STM32F769 and debug worked fine. I have just switched to an STM32F746 and OpenOCD reports: Open On-Chip Debugger 0.10.0+dev-00608-g68f09de (2018-12-10-13:40) ... Info : STLINK V2J29M18 (API v2) VID:PID 0483:374B Info : Target voltage: 3.238270 Warn : Silicon bug: s

OpenOCD mpc5xxx support

2021-04-06 Thread James Murray
In the digest email today, I saw a commit of files for the NXP (Freescale) 56xx and 57xx targets. What's new since my work of 2015-7 ? At that time, 56xx was working enough for me to debug that a MPC5634M. 57XX was very incomplete and I think I'd only really got as far as talking to the chip. I
