TI中文支持网Part Number:TMS320F280025
我做了一个bootloader程序，需要把整个工程放在ram里面运行。用作boot升级boot，升级过程中会擦除flash的全部程序
运行完全没有问题。但编译有告警。不知道是否有问题。用官方例程改成这个cmd文件都会出现这个告警
我是按照这个网页操作的 https://zhuanlan.zhihu.com/p/495521132
还有没有别的什么方法把整个工程放在ram运行。
以下是修改280025_FLASH_lnk.cmd文件的部分
//.text : >> FLASH_BOOTLOADER, ALIGN(8)
.text : LOAD = FLASH_BOOTLOADER,
RUN = RAM_DATA,
LOAD_START(_text_loadstart),
LOAD_SIZE(_text_size),
RUN_START(_text_runstart),
ALIGN(8)
编译告警的内容
