CCS 6.1
AM335x, WKUP_M3
gcc version 4.9.3 20150413 (prerelease) (Linaro GCC 4.9-2015.05)
I added a local variable into a function in order to make a spin loop, e.g. like this:
volatile int stop=1
while (stop) {}; // connect here with JTAG
For some reason, when I put the "stop" variable into the debugger it was looking at the wrong address! Here's a screenshot that I think captures the issue well:
So in particular, here are a few points of interest in the screenshot:
- In the "Expressions" window, the stop variable shows a value of 18 despite the fact that I assign it to be 1. However, the address it's viewing is 0x80FAC which is not correct.
- If you look in the disassembly window at address 00001c18 you can see that the value it's loading is SP+4. So if you look in the Memory Browser window you can see that 000080FC4 contains the expected value of 1.
- In the Registers window you can see that SP = 0x00080FC0 and R3=1 (as expected from the disassembly).
Any idea what's wrong here? Here is my elf file: https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/81/am335x_2D00_pm_2D00_firmware.elf
