你好，我有看到lab0012_can_sbl里面有一个1843的CAN BOOTLOADER例程，我要如何才能将它改成1642能用的CAN bootloader例程呢？
Shine：
可以尝试把sbl_xwr18xx.c文件用sbl_xwr16xx.c文件替代，再重新编译。

user4861090：
谢谢，其实是主要我不知道如何把1843的工程环境环境改成1642的工程环境~~只替换C文件，无法编译通过。
以下是我的尝试步骤：
1.将sbl_xwr18xx.c文件用sbl_xwr16xx.c文件替代，编译后提示一些1642的宏定义没有，如SOC_XWR16XX_MSS_EXT_FLASH_BASE_ADDRESS。
2.我将properties->predefined中SOC_XWR18XX改成了SOC_XWR16XX，properties->general->variant 中的1843改成了1642，
在将transport.c中1843的关于CAN的引脚初始化先注释掉。再编译提示以下错误，我就不知道该怎么修改了。

Shine：
1. transport.c里的管脚配置用下面的代码代替
/* Setup the PINMUX to bring out the XWR16xx CAN pins */Pinmux_Set_OverrideCtrl(SOC_XWR16XX_PINE14_PADAE, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);Pinmux_Set_FuncSel(SOC_XWR16XX_PINE14_PADAE, SOC_XWR16XX_PINE14_PADAE_CANFD_TX);
Pinmux_Set_OverrideCtrl(SOC_XWR16XX_PIND13_PADAD, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);Pinmux_Set_FuncSel(SOC_XWR16XX_PIND13_PADAD, SOC_XWR16XX_PIND13_PADAD_CANFD_RX);2. 用\labs\lab0012_can_sbl\src\ mss_can_sbl_linker.cmd文件代替xwr1642_r4f.cmd
