**lettleShell移植支持说明：** 需要适配esp32的ld文件。
|
|
|
|
|
|
|
|
|
|
|
|
样例：
|
|
|
|
|
|
C:\Users\Administrator\esp\esp-idf\components\esp32\ld\
|
|
|
|
|
|
在这个文件夹里面，把原来的esp32.project.ld.in替换当前目前的id文件，用于支持命令行，替换前记得备份
|
|
|
|
|
|
|
|
|
|
|
|
```c++
|
|
|
|
|
|
/* 核心原理是找到这个.flash.appdesc, 然后加入_shell_command_start和*_shell_command_end/
|
|
|
|
|
|
.flash.appdesc : ALIGN(0x10)
|
|
|
|
|
|
{
|
|
|
|
|
|
_rodata_start = ABSOLUTE(.);
|
|
|
|
|
|
|
|
|
|
|
|
*(.rodata_desc .rodata_desc.*) /* Should be the first. App version info. DO NOT PUT ANYTHING BEFORE IT! */
|
|
|
|
|
|
*(.rodata_custom_desc .rodata_custom_desc.*) /* Should be the second. Custom app version info. DO NOT PUT ANYTHING BEFORE IT! */
|
|
|
|
|
|
|
|
|
|
|
|
_shell_command_start = ABSOLUTE(.);
|
|
|
|

|
KEEP (*(shellCommand))
|
|
|
|
|
|
_shell_command_end = ABSOLUTE(.);
|
|
|
|
|
|
|
|
|
|
|
|
/* Create an empty gap within this section. Thanks to this, the end of this
|
|
|
|
|
|
* section will match .flah.rodata's begin address. Thus, both sections
|
|
|
|
|
|
* will be merged when creating the final bin image. */
|
|
|
|
|

. = ALIGN(ALIGNOF(.flash.rodata));

} >default_rodata_seg
