As someone new to embedded Linux development, I’m diving into the world of cross-compiling for the SAMA5D27 Cortex-A5 processor. I’ve been using Microchip for years, but I’m eager to expand my knowledge with Linux and FreeRTOS. My goal is to set up FreeRTOS on the ATSAMA5D27-WLSOM1-EK1 development board, but I’m hitting some roadblocks with the cross-compiler and flags.
I’ve tried several configurations in my Makefile, but I keep getting errors related to special purpose registers not being supported. For example, the error msr DAIFSET,#2' is popping up, which I understand is related to the CPU architecture. I’m also seeing warnings about redefined macros in the FreeRTOS configuration files. It seems like the compiler isn’t recognizing the Cortex-A5 architecture correctly.
I’ve tried using different versions of the ARM toolchain and adjusting the MPU_TARGET flags, but nothing seems to resolve the issue. I’m wondering if I need a specific version of the toolchain or if there are additional flags I should include. Any guidance on selecting the right cross-compiler and flags would be incredibly helpful. I’m also curious if anyone has successfully set up FreeRTOS on this board and if they have any tips or resources to share.
Additionally, I’m still getting comfortable with Linux Mint, so any installation or setup advice would be appreciated. I’m determined to get this working and would love to hear from anyone who has tackled similar challenges. Let’s make this project a success!
