Component: <strong>RTOS</strong><br />
Category: CPU core<br />
Synopsis: Make workarounds for CPU instructions (CLI, MOV SS, POP SS).<br />
Description: There are two CPU core problems that need a workaround inside the <strong>RTOS</strong>.<br />
1) CLI sometimes does not take immediate affect for SC1x3 or SC13/SC11 CPU's.<br />
This depends on code alignment, which can't be controlled.<br />
2) MOV SS and POP SS don't mask the interrupts for this and the next instruction (load of SP).<br />
So an interrupt can possibly work on an invalid stack, which will lead to corrupted memory.<br />
Note: The SC12 does not have these problems.<br />
Fix: Place a NOP after the CLI, or otherwise position the CLI in advance by one instruction of where it<br />
must become affective. Mask NMI around stack switch operations.<br />
Note:<br />
The Paradigm compiler (7.00.026 and before) uses SS inside the malloc()/free() functions. This<br />
has been fixed with build 7.00.027 of the compiler.<br />
For masking/unmasking the interrupts, please use the compiler macros enable/disable. They<br />
have been adapted to pay attention to the CLI instruction problem.<br />
Borland users should use the patched libraries and include files that <strong>Beck</strong> will offer.<br />
