几个旧的AP，配置是 QCA9531+QCA9887，自带的百兆网口，本着垃圾佬能用不扔的“传统”，想折腾一下放在要求不高的地方凑合着用。原系统是瘦 AP ，别说功能合不合适了，完全没功能可言。。。。所以就想自己折腾一下 Openwrt ，之前也折腾过几个 MTK的MT7628、MT7621 ，都不难，没想到这高通的这么麻烦。特此发贴请教一下，请各位不吝赐教，谢谢。
首先说明，除了5G无法驱动外，其它功能是一切正常的，源码版本为 openwrt-22.03.1
原厂 art ：在 0x40000 开始，art 0x0 开始是连续的 LAN 和 WAN 的两个 MAC，0x1000 是 02 02 开头的 2.4G art 数据，长度0x440。0x5000 是 44 08 开头的 5G art数据，长度0x844。
为了刷机时不用挪 art 的位置直接引用原机 art，自定的分区格式 art 部分也是从 0x40000 开始的，长度 0x10000，详见以下DTS：

已折腾一个多星期，网上搜遍了，看了仅有的一些文章，也是没有解决问题，所以只好发贴请教如何“破解” 
请各位高手不吝赐教，谢谢。
