Sorry if this is a repost that I missed but I'm looking to play with one of these boards to practice porting RTOS's to such as uCOS II/III. But I don't know much about the debug capabilities provided by STLINK/V2 built into the STM32F4 Discovery board. Such as ....

1. Can I debug/single step starting at the reset vector?

2. Can I easily view registers/memory disassemble using STLINK?

Basically I've used JTAG debuggers in the past and wonder if just using USB to debug/program will give me similar debug capabilies.

Thanks.

While the pod facilitates those functions, it's going to depend on your IDE/debugger.

I can use the ST-LINK in Keil to do the aforementioned tasks, and step into code outside the project.

Thanks, looks like I should be good to go with ST-LINK outside of boundary scans which hopefully are not necessary in my case! 🙂

I basically want to be able to walk through bootstrap code just to see what's going on before getting to where an OS starts loading for my own education. (on the cheap)
