About the simple version of T-Monitor, how much is its function implementation simplified? After building the open-version T-Kernel, I transferred a generated kernel_rom.mot file into the flash memory of the T-Engine, but the T-Kernel did not start (no boot messages displayed). The simple T-Monitor also has a serial I/O function implemented. What is the difference with a serial I/O driver? About the method for building the Renesas compiler version of T-Monitor. When the T-Kernel for the FPU-incorporating microcontroller (SH7751R or SH7760) is built with GCC4.0.0, etc., a compile error occurs.
