I have a PPP over GPRS program in Ver 4.7 of keil and after i port it to Ver 5.1 with new libraries it will crash without any known pattern with IMPRECISERR bus fault.
Is there any known bug in this vertsion of RL-ARM ?
I Use CMSIS-OS with 2 threads.
I Have the same problem with Ver 5.1 i think that there is a bug in net_main(), the program works for about 3 to 4 hours and then hangs !!!
almost same problem for me too did you try increase number of treads and heap size for treads it may helps
