Zephyr/NXP项目：将自己的板子添加到板子路径中（基于IMXRT1170_evk）
Zephyr/NXPproject: add own board to the board path(based on the IMXRT1170_evk)
问：
我正在尝试将一个新板添加到zephyr项目的板文件夹中。
目标：我想通过微控制器 （IMXRT1176 FLEXSPI1...A - CM7），并使用 tcm 代替 SDRAM 或任何外部 RAM。我没有使用恩智浦的evk，而是使用另一块板。
将 jlink v. 7.66 与自己的设备一起使用，以进行引脚多路复用更改。
到目前为止，我尝试了这个：
1. 更改 pinctrl.dtsi
我更改了 pinctrl.dtsi，因为正在使用的 flexspi 具有另一个引脚多路复用。我找不到有关更改 devicetree 的 pinmuxing 的内容......这种改变是基于希望。
#include <nxp/nxp_imx/rt/mimxrt1176dvmaa-pinctrl.dtsi>
...
};
pinmux_flexspi1: pinmux_flexspi1 {
group0 {
pinmux = <&iomuxc_gpio_sd_b2_05_flexspi1_a_dqs>,
<&iomuxc_gpio_ad_18_flexspi1_a_ss0_b>,
<&iomuxc_gpio_ad_19_flexspi1_a_sclk>,
<&iomuxc_gpio_ad_20_flexspi1_a_data00>,
<&iomuxc_gpio_ad_21_flexspi1_a_data01>,
<&iomuxc_gpio_ad_22_flexspi1_a_data02>,
<&iomuxc_gpio_ad_23_flexspi1_a_data03>;
bias-pull-down;
input-enable;
};
};
...
2. 更改了设备树

6. 新增xip
我添加了我们自己的flexspi_nor_config文件，这些文件被证明是有效的（它在裸机上工作）。
调试时，它看起来像这样：调试
7. 我还试过：
仍然不起作用。
问题：有人知道我做错了什么吗？ 我正在拼命寻求帮助！谢谢每一个线索！
