CIRCLE WITH A DOT

@whitequark think I’m going to have to give this one up. That crystal is a little too confined for my abilities with an iron.

@whitequark I tried running at --freq 1000, in a loop, and noticed that the error changed from "communication error" to "target failed to acknowledge debug power-up request" after a while, and then stayed with that error.

btw, I'm gobsmacked by glasgow running in the browser. That's a monumental achievement! Well done!

@whitequark Ok, thanks for your help. I'll give that a go. Much appreciated. Have a great evening.

@whitequark I used `glasgow run swd-probe -V A=3.3 dump-memory 0x08000000 4096`

@whitequark swd-probe fails with "communication error".

How would I provide an 8MHz clock? I presume I would need to disable the 26MHz one somehow? Direct connection to the OSC_IN pins on the microcontroller?

@whitequark Unfortunately, probe-rs was also unable to control my chip.

@whitequark I'm just trying everything to get control of the chip again Am busy installing probe-rs currently

Hi @whitequark I'm trying to use a Glasgow to program an STM32F205RG that has been flashed with a bad firmware.
I was trying to make a cdcacm gadget, and flashed with a libopencm3-based firmware, having selected the HSE clock as 8MHz. Turns out the board has a 26MHz crystal, and now it is not responding to st-info or BMDA, via an ST-Linkv2 probe.
Hoping the Glasgow big gun may have more luck, but it seems that the swd-probe applet doesn't have an option to configure a reset pin?

@whitequark crazy how the cables jumped when he turned them on!

@malwarejake I hope you get the care you need. You would be sorely missed.

@G33KatWork completely fair. You don’t owe anybody anything, least of all an explanation, but I appreciate it nonetheless. Truth is I have zero knx gear, and am unlikely to acquire any legitimate kit here in South Africa. But I do like the idea of it, and would be keen to try some home brew version if/when available.

@G33KatWork I have a spare Pico w lying around, would be curious to try this …
