#44416 — Mecrisp setup on TI MSP432 Launchpad

So I got myself a TI MSP432 Launchpad for christmas. 
The mecrisp page says it is supported MSP432P401R, which 
I found in the download. The problem I have is that I 
have not found specific (i.e. - step by step) instructions 
how get mecrisp installed and running on this thing.

Any help or advice on how to get off the ground would be greatly 
appreciated.

In the recent flurry of activity here I missed this post until now.  I 
feel your pain.  Mecrisp is an interesting tool and supports a number of 
platforms, but is not well documented by any means.  But I believe there 
are some installation instructions somewhere.

Without digging around for the instructions, I believe there is a file 
in the Mecrisp package that is ready to be downloaded to the target. 
You simply need to get your hands on a suitable installation tool to do 
that.  I recall that TI supplies a tool, but they do a poor job with the 
Windows part and you need to use an unsigned driver which is a big PITA 
under Windows 8 which I have.  If you have an older version of Windows I 
think using this driver is easier.  I ended up using a driver for Linux 
on a Raspberry Pi (rPi).  The rPi worked so well for this that I ended 
up using it as an interface for the Launchpad and worked on my PC 
remotely.

My rPi is packed away at the moment, but it would not be too hard to 
resurrect the steps I took to get it running.  In fact, I want to 
document this fully and make it available somewhere.

Have you tried searching on the web?  I think I found everything I 
needed that way.  I may have exchanged some email with Matthais, but in 
general his replies are not quick and I think he prefers not to get 
bogged down in supporting each user.  If you still can't find anything 
I'll dig around to find the info I used.

As Rick says, you need the mecrisp-stellaris image file, and a
tool to upload this to your micro. The NXP ARM I installed this
on was easy, both using a NXP tool for windows and a command
line tool for linux. 

I couldn't find TI tools on their site, but found this:

http://energia.nu/

I'm not sure how close this development is to TI, but it says it
is open source. It is a complete IDE, so whether you can find
the uploader or build it quickly as a standalone I couldn't
figure. 

If all else fails get a $8? DIL28 NXP part and do initial
mecrisp-stellaris install on that.

Might be easier to just get a Stellaris (Kiva) Launchpad.  But it
would be nice to run Mecrisp on the MSP432 Launchpad.

Flashforth also seems really nice, and Mikael has been posting here
lately.  I'm not sure which (if any) of these boards it runs on, though.

Exactly. Flashing instructions are in the README file in
the main directory of Mecrisp-Stellaris, and you can use
the tool supplied with recent Energia for Linux.

;------------------------------------------------------------------------------
Hardware and configuration for MSP432P401R:
;------------------------------------------------------------------------------
  Connect your cable to the USB-Port,
  set "JTAG switch" to XDS position,
  close 5V, 3V3, RXD, TXD jumpers.

  Flashing is possible with DSLite, which is part of Energia 15:
  DSLite -c MSP432P401R.ccxml -f mecrisp-stellaris-msp432p401r.bin -l 0 

  On startup, this runs with DCO on 12 MHz.

Thanks for all your responses. With the holidays, things have been
kind of busy. Now that things have settled down a little, I hope to 
get this thing up and running this week.

Thanks for the pointers.

I am on a Windows 10 system. This evening after work, I'll see if I 
can find and install this Energia system for that DSLite program.

Thanks for asking! Alas, other priorities have cropped up that have been taking my attention.
My son is on winter break, and he bought a kit to build an API compatible audio compressor
which I have been helping him put together. I am also working on putting together a slide
show for a celebration of my late mother's life next week.

But believe me when I say that I am extremely interested in making this happen, so this
will not be on the back burner for long.
