all: is libusb interface (or something like that) exposed to tcl?
<PaulFertser>
No, at least not by OpenOCD itself.
<PaulFertser>
So there's no integration or anything to allow sending raw USB from Tcl.
<PaulFertser>
It shouldn't be normally needed.

anyone happen to know what's this Geehy business? APM32, part numbers remind strongly of ST, are they yet another set of clones? or do they try to improvise?
<Haohmaru>
local distributor appears to have them, they are extremely cheaper than similar spec chips from more "classical" vendors
<karlp>
they're not clones.
<karlp>
they're just a different vendor.
<Haohmaru>
because i know some of them do stuff like try to "make a firmware for STM32xxx" work on their chip, almost, i've heard stories where there's like small differences to the USB peripheral but everything else "works"
<Haohmaru>
tbh i don't like this, it allows them to be irresponsible and not provide documentation becase "just gtfo and read the ST documentation"
<Haohmaru>
i found out about them because i randomly saw "APM32PROG / geehy-link" and i checked it out, it appears to be a daplink, it's like 15euro at local distributor
<Haohmaru>
but its documentation is kinda sketchy

yeah it seems these are another ones where "firmware for STM32 seems to work" ...
<Haohmaru>
so who knows what's gonna break when you least expect it ;P~
<Haohmaru>
altho i think similarly to GigaDevices, they do seem to have some more "original" MCUs, i think i saw a 250MHz cortex-m52

zapb_: 17:42 < indy> i would prefer to be able using jimtlc to access usb to load that code instead of loading it using rk tools
<PaulFertser>
The code to enable SWD/JTAG
<zapb_>
rk?
<PaulFertser>
Rockchip
<PaulFertser>
Its boot rom can do usb device and then you can load something to its SRAM and run. And JTAG isn't enabled by default.
<zapb_>
ah, check
<PaulFertser>
But there're no libusb bindings for jimtcl.
<PaulFertser>
afaict
<zapb_>
could be done by executing a binary via tcl before connecting via openocd
<PaulFertser>
Yeah, and there are independent free software tools to talk to rockchip rom. But it won't be self-contained then, OpenOCD alone wouldn't be enoough.
