08:44 <PaulFertser> doug16k: why do you think this driver supports SWD?

08:44 <PaulFertser> doug16k: are you using some fork or unmerged change?

08:50 <doug16k> I thought I found openocd source that said it added SWD to bitbang

08:50 <doug16k> assumed they just forgot to update that txt

08:51 <doug16k> does that mean I can't bitbang cortex M0 with remote bitbang?

08:52 <PaulFertser> doug16k: why do you consider remote bitbang in the first place and not running OpenOCD on the machine that is connected to Cortex-M0?

08:52 <doug16k> connected to how?

08:53 <PaulFertser> doug16k: I mean local bitbang instead of remote.

08:53 <doug16k> I am making a esp32 wifi remote bitbang server to hack into swd pins

08:53 <doug16k> how do you connect your pc to swd

08:54 <doug16k> my rpi are all dead

08:54 <doug16k> died by themselves

08:55 <PaulFertser> doug16k: https://review.openocd.org/c/openocd/+/6044 this can be picked up and updated to be usable with current version.

08:56 <doug16k> ah so I probably stumbled on someone's proposed swd bitbang patch and I thought it got in

08:57 <PaulFertser> Remote bitbang is kind of slow anyway, I'd probably find some board to run CMSIS-DAP/DAPLink firmware on it instead.

08:58 <doug16k> I should have known right away when openocd was saying only "jtag" is available

09:00 <karlp> I normally use an openwrt sort of platform with a stlink on usb...

09:00 <doug16k> I'm right on the edge of dropping the M9

09:00 <karlp> doesn't have to be rpi stuff.

09:00 <doug16k> they made a huge barrier to bothering to use it

09:01 <karlp> "they"?

09:01 <PaulFertser> doug16k: hm, probably you can use https://github.com/windowsair/wireless-esp8266-dap ?

09:02 <karlp> neat, glad something like that exists.

09:02 <karlp> I think I've seen parts of BMP ported to esp32 as well.

09:03 <doug16k> microchip's exorbitant baseline price drove up the price of the clones sky high

09:03 <karlp> umm. wat?

09:03 <doug16k> it's $400 to buy the tool

09:03 <doug16k> the official one

09:04 <PaulFertser> What tool? What are you talking about?

09:04 <doug16k> atmel-ice

09:04 <doug16k> that's the official "swd your microchip M0 MCU"

09:04 <PaulFertser> Ah, that. You can use any SWD adapter I think. Even stlink in DAP mode.

09:05 <karlp> they provide a cmsis-dap debugger on all the (mini)explained boards too, for like <$10.

09:07 <karlp> ok, it's $13 now. https://www.microchip.com/en-us/development-tool/ATSAMD10-XMINI

09:11 <doug16k> the crazy part is, I don't even have an M0 anywhere near me yet. I am designing a display board and it'll offload the display and SD and FS I/O from the main MCU

09:11 <doug16k> getting custom boards made and they will have M0 on them

09:11 <doug16k> I will put the header on it

09:11 <doug16k> and I'm not even 100% sure I will be able to flash it without a whole project of work

09:12 <doug16k> going to design custom pcb with an MCU that technically I can't flash, yet

09:12 <doug16k> sounds cuckoo

09:16 <doug16k> I'll probably figure it out. I'm so pessimistic with predictions

09:16 <doug16k> that patch you gave will help a ton

09:17 <doug16k> linked*

09:17 <karlp> if you put the swd header on it, it will be fine.
