I try to port FreeRTOS on a SAM3U-EK board with Keil toolchain.
I use an existing working project and I have included FreeRTOS sources.
Unfortunately, portASM.s file i use (from CORTEX_AT91SAM3U256_IAR\Source\portable\RVDS\ARM7_LPC21xx\) seem d’ont compile with SAM3U. I have the following error:
“portASM.s(69): error: A1630E: Specified processor or architecture does not support ARM instructions”
Have there an working port of portASM.s for SAM3U?
