LM4F and TM4C — Is lm4flash to be replaced by OpenOCD? #381

Closed rei-vilo closed 9 years ago

rei-vilo commented 10 years ago

From #270 7 months ago:

lm4flash will be replaced by OpenOCD in the next rev. Unfortunately there is nothing I can do at the moment about the lm4flash included in Energia 0101E0010. As an interim solution I suggest as you did and take lm4flash from the previous distribution.

Is lm4flash to be replaced by OpenOCD?

Release 12 still has lm4flash.

I'd like to chime in and say that OpenOCD doesn't work at all on my desktop, despite hours of debugging - no matter what I do, it just won't connect. If OpenOCD were made the only option, people like me would be stuck using older releases.

There are 2 commits currently available in the OpenOCD gerrit review system that add support for this:

I have successfully used this patch with bleeding edge git version of OpenOCD. To get this to work: 1: git clone git://git.code.sf.net/p/openocd/code openocd-code 2: Apply the patches mentioned above. 3: cd openocd-code 4: ./bootstrap 5: ./configure --enable-maintainer-mode --enable-ti-icdi --prefix=<wherever you want this to be installed e.g. --prefix=/opt/openocd> 6: make 7: sudo make install

The request for merge has been denied by the OpenOCD maintainers since they do not see a reason for adding another file. Instead they have asked the author to incorporate the change into the existing flash driver (stellaris.c).

Using openocd to upload a sketck works very well.
