Multicore SVD file parsing

[kduca-winkadukeconsulting]

Description

No peripherals displayed in Peripherals view while debugging an NXP LPC4350 (multicore: M4 and M0) even though the LPC4300 Series Device pack is installed and associated with the project.

Steps to Reproduce

1. Make sure LPC4300 Series Device pack is installed (v2.7.0 used).
2. Make sure LPC4350 Device is associated with the M4 code project (Project Properties->C/C++ Build->Settings).
3. Launch M4 debug session and verify it successfully connects to target and stops at main().
4. Select Peripherals view.

Expected behavior:
List of peripherals are displayed, or a way to select/expand peripherals in the view.

Actual behavior:
The Console view displays Parsing SVD file "/Users/kd/Documents/GNUARMEclipse/Packages/Keil/LPC4300_DFP/2.7.0"... but often Failed to get the peripheral descriptions displays briefly in red at the bottom status line of the Console view.

The .log file shows:

Hi,

i experience the same problem with LPC4300 and imx6 and imx7 packs. Maybe it helps as a hint, If i use the 2.6 Version of the LPC4300 Pack the parsing of the svd file works fine. With the 2.7 Version it stopped working.

I acknowledge the bug, multi-core devices were not considered when writing the plug-ins.

fixing it requires some more efforts; it'll be done, but it might take a while.

Thanks for the quick answer. What i dont understand right now, if multicore devices were not considered why is version 2.6 of the pack working ?

[ilg-ul]

I guess by pure chance.

Hi,

regarding this topic again, i had a look into the IMX6_DFP pack from Keil. If i'm not wrong in the SVD folder there is one .svd file per core. Shouldn't it then be possible to parse the xml like for a single core ?

[ilg-ul]

I don't think the problem is due to parsing multiple files, I guess that selecting the right one confuses the plug-in.

[hriekehof]

Ah ok i see. But this seems easy to fix :) Sorry for bothering you so hard on this topic but i really would need it :)

[ilg-ul]

it is on my todo list, but, unless some unexpected contributions that might boost priorities, the priority is not very high.
