I have the features i need in linuxppc_2_4_devel and rtlinux (3.x). I downloaded the rtlinux patch from denx. But looks like it is for linux-2.4.4. Any idea how hard it is to port it myself?

* User mode accesses cause a SIGSEGV 2003-02-18 1:46 ` RTLinux patch for linuxppc_2_4_devel Prakash kanthi @ 2003-03-12 18:11 ` Prakash kanthi 0 siblings, 0 replies; 3+ messages in thread From: Prakash kanthi @ 2003-03-12 18:11 UTC (permalink / raw) To: linuxppc-embedded Hi Folk, I have a problem with user mode processes on my PPC405 based board with 16MB SDRAM. I am using busybox based 'init'. When linux boots, init tries to swapn 'sh'. Shell starts ok but after that, any 'application' started under 'sh' bails out with error "User mode accesses cause a SIGSEGV for <some address>" The address it bails out is always same and generally is a huge value (ex: 0x92612077). I am suspecting that there might be something wrong with user mode PTEs. I am not sure when PTEs are created how they are privileged. Any help is appreciated. Thanks, Prakash Yahoo!
