CM311-1a启用蓝牙遇到问题，求助

[twallpasser]

盒子是从咸鱼上买来刷好了armbian系统的。
参考#1513提供的方法，我发现系统里已经有rtl8761b的固件和配置了，然后ttyAML1设备也有。rtk_hciattach是拉了这个仓库https://github.com/radxa/rkwifibt.git用里面的源码`realtek/rtk_hciattach`编译的。
按照前面的方法我写了各测试的脚本

armbian:~:# cat ./hci_test.sh
#!/bin/zsh
/usr/bin/rtk_hciattach -n -s 115200 ttyAML1 rtk_h5 &
gpioset -s 1 -m time 0 82=0
gpioset 0 82=1

但是执行到下载固件的时候就出错了

armbian:~:# ./hci_test.sh
