I’d like to use FreeRTOS on an AT91SAM7 with gcc. i have the arm-elf binutils and compiler but still no libc. Which libc do you suggest? background of this question: i only need the basic libc functionality required by freertos and the freertos demos. i’m still a bit new to this all, but as far as i read and found: - glibc is said to be huge for a 64K (or even 32K) device - uclibc is a priori made for (uc)linux only and would need severe porting to work with freertos (?) - newlib is also said to not be very small(?) so which libc is the best for freertos on SAM7 with gcc? thanks, frank

I think only  the functions you use from the library will get included in the build, not the  entire library.  Maybe therefore not a problem. Take a look at WinARM and GNUARM distributions to see what they use.

gnuarm uses newlib, so i’ll take that thanks
