Newbie question about task/queue table viewer in LPCXpresso. I’ve seen people talk about StateViewer plug-in, prebuilt, shipped as part of lpcxpresso ide but for the life me I just can’t find this plug-in or menus.
I’ve installed lpcxpresso v6.0.4_159 and v7.9.2_493. In v7.9.2_493, tried Windows -> Show View -> Other -> OpenRTOS Viewer / Task Table but under Windows -> Show View -> Other there is no “OpenRTOS Viewer”?
To my knowledge NXP (or CodeRED) had included that plugin, but I believe they had to remove it for licensing reasons. You can download and install that plugin yourself, see
Thanks. I’ve installed Wittenstein/High Integrity System Plugin now. I’m using LPC-Link from NXP for lpc1769 - kind of jtag built on dev board with aforementioned micro on it.
I’ve got freertos from sample code off NXP site, opening tasks.c, it appears to be FreeRTOS V7.5.3.
Stopping the debugger. When I open the task table or queue table they are both empty? I’ve read the Wittenstein install guide but they don’t seem to have trouble shooting section.
The plugin works for GDB type of debugger, and there is the DSF and the non-DSF version of the plugin. Do you know what kind of debugger you are using? You might try the one or the other version of the plugin. The other thing might be that the plugin cannot find your task table. In the GDB Traces view of the Console view you could see what variable the plugin is looking for.
Program received signal SIGTRAP, Trace/breakpoint trap.
