mxCube import to Arm Gnu Eclipse

Hello there,

Arm gnu eclipse ( http://gnuarmeclipse.github.io ) is a plugin for eclipse similar to openSTM32. It has its advantages, for example that user can use way more debuggers than only ST-LINK. I was wondering either ST would consider making an importer for mxCUBE for Arm Gnu EClipse plugin the same way they did for openSTM32.

For example I have a huge problem now. I am using mxCube to import code for openSTM32 project in eclipse. I am using JLINK, so I have to use the module from Arm Gnu Eclipse plugin, as openSTM32 doesnt support it. And now I cannot view peripherals while dubbuging even though both plugins support it. I cant use Arm Gnu Eclipse one, because the project is created by openSTM32. I cant use the second one, as I am using Arm Gnu Eclipse debugger... I dont know whats a way out out of this.

I would have to either get rid of JLINK and get st-link, but jlink is a lot better. Or I would have to manually copy generated code to Arm Gnu Eclipse project...

So would it be possible maybe for ST to make an importer for Arm Gnu Eclipse? Not a bad idea?

can try after replacing

source [find target/jlink.cfg]

with

sourc

e

[find target/stm32f4x.cfg]

and add the following lines

transport select swd

adapter_khz 1000 you can modify 1000 by your desired frequency

# This is an STM32F4 discovery board with a single STM32F407VGT6 chip.
# http://www.st.com/internet/evalboard/product/2524jsp
source [find interface/jlink.cfg]
transport select swd
adapter_khz 1000
source [find target/stm32f4x.cfg]
# use hardware reset, connect under reset
reset_config srst_only srst_nogate

just a short question- does openSTM32 support JTAG? Because in the .cfg file I have changed swd to jtag but that did not work.

Also, even though I am using jlink, the maximum breakpoints number is still 6.

yes openSTM32 supports JTAG, please check if your debugger wires are well connected to your device

>> Also, even though I am using jlink, the maximum breakpoints number is still 6.

yes even if you use Jlink or any other debugger the number of breakpoints is fixed to 6 (maximum breakpoints supported in CortexM4)

Yes the JTAG is connected correctly, as I am using it with standard jlink driver. Is there anything else that has to be changed apart from that one word in the file?

I have used for testing both of:

- IAR JLink (JTAG)

- IAR JTrace (JTAG/SWD)

And both of them have worked after modifying the driver to WinUSB by ZADIG

I see, but are there any additional settings that has to be set in order to use jtag instead of swd?

Just ensure that your cfg contains

transport select jtag

instead of

transport select swd

and your JTAG wires are connected
