If using the compiler with MPLAB X IDE, be sure to install MPLAB X IDE v1.50 or later.

MPLAB X may not be able to automatically locate the installation if it is not installed into the default directory.

The exception is the "small" data sections used for gp-relative addressing.

Because these sections must be grouped together, they are mapped in the linker script.

The linker may emit an unfriendly error message when it encounters a case where it cannot switch ISA modes between mips16 and mips32 in a function call.

The error message is "jump to stub routine which is not jal".

Please note, all ownership change requests must be submitted on the appropriate documentation, or via the on-line download form.

When adding a copy of the startup code to your project, be sure to set the project to not use the default startup code by specifying the const unsigned int k Phys Address = 0x9D07E000; // constant int Cal Data[4096]; volatile int result = 0; extern void foo (unsigned int a, int b); int __attribute__((optimize("-Os"))) Checks() int main(void) void foo (unsigned int a, int b) The assembler may emit an error, 'Macro used $at after"noat"', for a macro/synthesized instruction even when the synthesized instruction does not use the $at register.

A workaround is to replace the macro instruction with the actual instructions.

It will not interfere with existing Java or Iced Tea installations.

By default, MPLAB X will be installed at /opt/microchip/mplabx.
