环境： SEGGER Embedded Studio for ARM v7.10， nRF5 SDK 17.1.0
使用SEGGER编译示例ble_app_uart，出现一下问题及相应的解决思路：
问题1: retarget.c:101:23: error: unknown type name ‘__printf_tag_ptr’
修改retarget.c:99
#if defined(__SES_VERSION) && (__SES_VERSION >= 34000)
#if defined(__SES_VERSION) && (__SES_VERSION >= 34000) && !defined(__SEGGER_RTL_VERSION)
问题2: “.text is larger than specified size” and “.rodata is larger than specified size”
在项目目录下找到flash_placement.xml” 找到两行
<ProgramSection alignment=”4″ load=”Yes” name=”.text” sizeof=”0x4″/> <ProgramSection alignment=”4″ load=”Yes” name=”.rodata” sizeof=”0x4″ />
将上面的sizeof=”0x4″ 删除
问题3: libc_v7em_fpv4_sp_d16_hard_t_le_eabi_balanced.a(fileops.o): in function `putchar’:”
修改”Library I/O” (under Project options >> Code >> Library) from “None” to “RTT”
