08:27 <borneoa___> antto: within zephyr OS examples there is a cmsis-dap. Not sure it includes also the UART. If your MCU is supported by zephyr, it should be straightforward to build the existing example for it.

11:00 <antto> doesn't say anything about UART

11:01 <antto> this is a daplink debugger running on a lpc11u35 which i'm 95% sure is a circuit cloned from some of the early mbed SWDAP/DIPDAP example boards

11:09 <antto> i can't even tell if i'm doing the firmware update procedure properly

11:10 <antto> there's a bootloader button on it, i press it and plug the device, it appears as a "CRP DISABLD" mass storage device, containing a 64KB "firmware.bin" file

11:10 <antto> i erase it and i have to put the new .bin there, so i tried straight up copy/paste from the file manager, i tried "cp" (i'm on debian)

11:12 <antto> should the new file be named "firmware.bin" exactly or can it be "blahblah_whatever.bin" ... i can't find much details anywhere

11:34 <antto> oh sh*t, i think i maybe f*cked up something... i cannot get the debugger back to a working state even with the original zl33prg firmware now

11:35 <antto> it runs in the "CRP DISABLD" mode every time no matter what i do (whether the button is pressed or not)

11:44 <antto> oh, i got it back... so the instructions maybe aren't very accurate, copy/pasting and other ways didn't work, found one page that said you have to also unmount the drive and "dd" onto the /dev/sdX with seek=4

19:30 <marex> hey, I have aarch64 core and I need to invalidate and disable icache/dcache/mmu, is there any way to manipulate SCTLR from OpenOCD ?

19:30 <marex> it seems like a relatively common thing, enable/disable caches that is, but I cannot seem to find any way to do it ... did I overlook anything ?
