Cause of Abnormal Program Operation
My program stopped operating properly after I changed the message size in the mailbox function. Why? (Dec. 20, 2000)●
Assume that I am developing an application program with MR30. When I change the output destination directory during the
compile or assemble process (specified options: -dir for compiler, -0 for assembler), MR30 will no longer link the real-time
OS kernel module. (Dec. 20, 2000)

Warnings for Compiling and Linking

etc. when I perform the build. What is the problem and how can I solve it? (Aug. 20, 2002)New!

During a compile, the "far pointer (implicitly) casted by near pointer" warning comes up concerning the system call in the
mailbox functions. Why do I get this warning?
●
During a link, the "value is undefined" warning comes up for symbols "__TCB_tmrq_for" and "__TCB_tmrq_back". Why do
I get this warning?
