R2C2 Programming/Debugging Issue

[WeeHau Kang]

Hi,

My name is Weehau. I am more of a Microchip programmer, and recently just purchased a R2C2 kit to kick start with Arm-cortex M3 programming. The reason why I opted for R2C2 is because I am interested in the high performance reprap electronics based on 32-bit ARM processor, comparing to what's available in the Reprap industry. The other more important reason is that I have some interesting ideas to be implemented and contributed to the development of R2C2. After reading through the tutorial/guide in R2C2 development page on setting up eclipse and OpenOCD, I have purchased a ARM-USB-TINY and finally able to get the JTAG connected to the eclipse.

this is the log data from eclipse console window

However I was able to get only until this point. The Debug/Flash failed when i launched the debug menu ( I followed the same steps to configure in the

"Programming and debugging using Eclipse and JTAG").

This was always shown in the console window:

I can't get debug to work properly and the more bad news is I am now stuck because of the original firmware shipped with the board was erased. Can somebody help?

Hi Wee,

 

When you make it work, please tell me how you did it!

 

I've purchased 3 or 4 JTAG adaptors and tried several development kits... nothing worked. Well... the Keil worked, but the free version could not hold all the code.

 

During the tests I've made while developing, I've found out that the best way was to use the serial port (there is a pair on the extension pins that gives you a second serial) back to the PC using a serial/usb dongle. I've also used the beeper to make some debugging... it is really hardcore and like the "hold days", just big fun!

 

Hoping to get some news from you.

Rui

Hello.

I wrote the page "Programming and debugging using Eclipse and JTAG":
http://www.3dprinting-r2c2.com/?q=content/programming-and-debugging-using-eclipse-and-jtag

I have experiencie with this tools, for AMRs like STM32F100 (ST),
LPC2103 (NXP), AT91SAM7S (Atmel), AT91SAM9260 (Atmel), IMX233
(FreeScale).

This output means that JTAG is working and can communicate with LPC.

Try to connect using Telnet to OpenOCD and run commands like erase
flash memory, etc and see the output.

Maybe you can try to lower the communication frequency of JTAG... that
"Warn : negative acknowledgment, but no packet pending" may mean
communications failed.

Hi Rui,

Thanks for your sharing. I will let you know when I can make it work. It's quite disappointing when we expected it to work, after investing so much money and time thou!

Dear Jorge/others,

Thanks for your reply. I have tried to set the JTAG frequency to 200khz but still came back with same issue.

I have attached my eclipse configuration here. Also R2C2 firmware v1.0.3. Can you take a look of what is likely to cause the problem? e.g Makefile or startup file etc.

I will be very grateful and appreciate if any of you can spend some time to shed some light on this. I have been working on this for almost 2 weeks but not getting any progress. It's really frustrating and disappointing after spending so much money to purchase the kit but it turned out not working. I believe Rui Ribeiro and others will feel the same. Appreciate if you can do something about this.

Thanks in advance!

Dont give up yet, Jorge will help you. 

One of my problems was that I didn't had much time or "motivation". 

For me OpenOCD didnt't work, neither on Windows neither on Linux, but I'm not sure that I had the correct binaries (tried a few though). 

Maybe a cool thing that R2C2 team/support/community could provide to the community would be a ready to use virtual machine. 

- linux based

- eclipse / openocd

- git enabled

This is a chalange for you, Jorge!

Can somebody help? Anyone who has successfully compiled and loaded the firmware into the board mind to share how you did it?

Thanks.

Hi.

The first thing is to build the bootloader and flash it - you can use
JTAG or serial port for it. After you have the bootloader working you
can flash the firmware easily - follow this instructions:

I never found Eclipse/openocd/arm-jtag-tiny a very reliable system. I could get it working for a bit then it would all hang up and require restarting. I used openocd to Flash download the bootloader. Altogether the experience was very frustrating and I wasted a lot of time trying build and configure the software, and getting help is pretty hard. Unfortunately, these are about the only open source tools available, so if you want to go that route you will most likely have to get under the hood and figure things out yourself.

Programming the R2C2 with Eclipse/open-ocd is pretty much the same as any other LPC1758, so you might be able to get help from other places, e.g. the NXP forums.

For most of my development I used Rowley Crossworks, which is not free, but much more reliable. I also bought a Segger Jlink and Rowley JTAG adapters which perform much better. Again, not cheap, but I figure I want to spend my time writing code not debugging tools, and has been a worthwhile investment for me. I use similar professional tools at work, which I guess is an advantage.

There are some free versions of commercial tools, such as Keil and IAR, although these are size limited they might at least help you flash the bootloader.

The same is true for others ARMs from other vendors, like STM32
(cheap, popular on DIY) and SAM3X8E (Arduino Due):

Dear Bob,

Thanks for your useful information. I am still having trouble to get the debug running. I think i will probably give up using the open source platform and opt for crossworks. Can you teach me how to port the existing R2C2 project into crossworks? The crossworks can only load .hzp and .hzr files which i couldn't locate in the R2C2 firmware folder. 

Do you use skype for chat? my skype ID : KANGWEEHAU.

Thanks

If you look on the edge branch you should find a Crossworks project file. The edge branch has diverged quite a lot from master, but the project should provide a guide. You will need to change some project files and also some of the include paths. If I have some time I will try to put together a working project for the master branch.

Sorry, I don't use skype.
