Without DWARF/unwind tables, you're going to have a very hard time creating a backtrace, I'm afraid. You could back up the entirety of the stack and send that over on next reboot for analysis on the PC, but other than...
You have the stack pointer and you can use the compiler option -funwind-tables -- this was the working plan. More than that requires a disassembler and dwarf info on elf.
I have other priorities ATM but if I get some time this weekend I'll see about hammering away at generating dump files. A shame about the USB issue, though. Would be a massive help when rapid fire debugging (but I ended...
Hmm, buydisplay has a preassembled 1963 7".. I may give that a go, thanks for the suggestion. As my application is just a GUI, I don't really see it pertinent to have super fast update rates, but I'm always down to play...
There are a lot of moving parts which is why I agree it could be suspect. However: I've had quite a bit of success using SPI with several of the fault handlers (and even USB serial, even though I'm still unable to...
The code isn't horrible, it's just clearly pumped out quickly. I've turned it (their RA8875 lib) into a gruesome abomination of what theirs originally is, and then shoved an abstraction layer on top of that so I can use...
It's still a WIP -- I'm actively working on hammering away at it (my ARM asm knowledge is very slim, but I'm working on it!) but will definitely share once it gets in a more usable state. If I do want to use SD card to...
Hi! I'm not sure if this is the right question to ask, but I currently implement a hard fault function to do a (WIP) crash trace dump, but after the dump I'd like to re-enable USB interrupts so I can re-flash the Teensy...
I ended up having to create a driver to use my PC to render for testing because the RA was just so slow lmao (and it doesn't even support scissor rects? ew!)
While not unlikely, I feel the requirements to get NXP...
Some people just like eating more than cinnamon toast crunch :rolleyes:
The dual core nature of the new MCU means we can rather easily offload software emulation of various protocols like UART/SPI/etc on the other...
It would be interesting to see a Teensy variant with more pins exposed (e.g. a teensy 5.2?) The NXP chips have so many capabilities limited by the smol formfactor of the Teensy.
While good for 99% of usecases, I'd...
