February 18, 2026 Commented > It also requires support from e2 Studio’s gdb-server, which is not implemented currently. Understood. Dynamic printf can be good alternative solution. UART can be used, but need some implementation. cf. https://community.renesas.com/mcu/risc-v-mcu/f/forum/58631/hello-world-example Thank you for support. This query can be closed.

January 26, 2017 Commented Thank you for the responses. Let me confirm a little more. Basically, _sbrk() and _sbrk_r() found in Newlib source code located below do the same thing as optlib, right? \arm-none-eabi\arm-none-eabi\bin\newlib\libc\sys\arm\syscalls.c \arm-none-eabi\arm-none-eabi\bin\newlib\libc\common\sbrkr.c

January 24, 2017 Commented I may have misunderstandings about malloc behavior. So, only need to do is not to place anything between .bss and .stack? Is there any documentations or design guides about implementing _sbrk()/_sbrk_r() functions for this library?
