Hello, I use RTX166 on my system (20 tasks). How can i check Task Stack busy level to prevent a possible stack overflow? Operating system manual say: "Register R0 is stack pointer" I will check Run-time R0 value to find max value. but I think is much better to use a Source Code Analyzer like: http://www.absint.com/stackanalyzer but it doesn't work with Keil. Can you suggest me a stack analyzer for my system? Best Regards
