Hi !
I was in need of a cheap JTAG probe to replace my scruffy Wiggler cable,
so I wrote an opensource firmware for STM32F103 developpement boards,
which are widely available under the "Blue Pill" name. You can get the
firmware here : https://github.com/jeanthom/DirtyJTAG
I wrote support
Hi,
I got one off Aliexpress, and what I received was an adaptater with a
PIC (it uses this firmware : http://sa89a.net/mp.cgi/ele/ub.htm). It
doesn't works with UrJTAG, neither with OpenOCD. I got the cheapest
Blaster I could find, maybe higher end adapters have the FT2232 ?
Anyway if what
Cheap could be good for gang testing and gang programming of flash
MCUs. Does your imperfect implementation of the JTAG protocol
allow for a daisy chain of MCUs with a termination resistors at the
end to test one of them at a time?
It should work, but I cannot ensure it. My implementation is not
Hi !
I came up with some modifications on UrJTAG source code to support
SST39VF160x and SST39VF320x flash chips. Those chips needs some special
unlock addresses (0x/0x2AAA instead of the regular CFI
0x555/0x2AAA). The applied patches shouldn't break existing CFI flash
compatibility.
Hi !
I sent a link to my fork of UrJTAG with SST39VF{32,16}0x support
(https://github.com/jeanthom/urjtag-sst39vf160x-sst39vf320x) some time
ago.
I updated the CFI_VENDOR_SST_WEIRD constant to CFI_VENDOR_SST_MPFP, but
I recall that other changes were needed, could someone elaborate on that
Hi,
I agree with Benjamin, SourceForge is dying and a blocker for potential
newcomers to the project.
I suggest migrating to whatever modern Git forge you prefer (GitHub,
GitLab, SourceHut) and having a mirror on at least GitHub so that
people can contribute there. I have seen many people
