Pre-Fetch Abort before main execution using ARTX and CARM with LCP2129

 Pre-Fetch Abort before main execution using ARTX and CARM with LCP2129

I get a pre-fetch abort almost every time I try to run my application, before running main(), if I use an ARTX function. During my tests I discovered that if I get a especific value on R0 the application runs, so I have to reset the processor several times until I get this value. If I take out the os_sys_init() function of the main, the application works fine. I've discovered later that the program executes the function os_clock_interrupt() a few times before it crashes. I'm using Keil Ulink for debugging and my soft versions are below:

I've found some similar problem with ARTX166 in:

The code looks like the os_clock_interrupt(), but I haven't found nothing for ARM7.
