a133 linux4.9 安装驱动
insmod usb_wwan.ko
insmod option.ko

之后能出来 ttyUSB，但是很快 USB 就断了，lsusb查不到设备，然后又连上，就这样断断续续。

同样这块板卡，我在 linux5.4上是正常能拨号上网的！换成 linux4.9 就不行了，我需要用4.9的内核

有大佬知道是怎么回事吗，救救孩子吧...

更改内核的同时将文件系统更改为了 ubuntu18.04，将文件系统改回 sdk 提供的就正常了，也能拨号上网。。。

问题出在 ubuntu

问题已确认，ubuntu有个modem管理，/usr/sbin/ModemManager 会去管理4G模块，grep 发现里面有 option1 的操作，赶时间简单粗暴直接删除就可以了

GPU 安卓部分是正常的，linux 部分才有这个问题，我使用的是 linux，不适用安卓。

A133 linux5.4 下的 GPU 无法正常使用（编译为 linux 固件，非安卓固件）

insmod pvrsrvkm.ko 打印 read BVNC 0.0.0.0，无法读取到 BVNC，指定使用 22.102.54.38

接着跑 QT 例程时打印读取不到固件 rgx.fw.22.102.54.38。

将固件 rgx.fw.22.102.54.38 放到 /lib/firmware/ 下，重启系统后再次安装 pvrsrvkm.ko 后跑 QT 例程，dmesg 可看到下面的打印信息

查看源码，有一些提示

直接翻译注释

当bFirmwareStarted失败时，可以通过执行以下调试转储获得一些信息，但不幸的是，如果未启动的原因是GPU电源未打开，则可能存在潜在危险。
然而，如果我们已经到达这一点，系统层已经返回没有错误，我们假设GPU电源确实是ON。

设备树 board.dts 配置如下

&gpu {
  gpu_idle = <0>;
  dvfs_status = <1>;
  pll_rate = <504000>;
  independent_power = <0>;
  operating-points = <
    /* KHz   uV */
    504000 950000
    472500 950000
    441000 950000
    252000 950000
   >;
   gpu-supply = <&reg_dcdc4>;
};

linux menuconfig：
1、打开 DRM

2、选择 GPU 为 ge8300

有大神知道怎么搞吗，linux5.4 下无法使用 gpu，而编译安卓的固件就可以，Linux的固件就不行。

@awwwwa 感谢回复！glmark2 安卓才有，linux 下测试只能自己移植吗，我这边使用的是 Linux，不采用安卓系统。

另外我参考文档，能不能直接找到 EGL 跟 GLES 的库，加上图中的例程代码直接编译运行？

我找到安卓下有提供到库，但很难编译通过（使用 longan/build/toolchain 中gcc-linaro-5.3.1-2016.05-x86_64_aarch64-linux-gnu.tar.xz ）

A133 不使用安卓系统，直接在 longan/ 目录下编译生成 Linux 固件。

想要测试 GPU，已经配置内核打开 DRM 跟 ge8300 gpu，系统运行后手动安装了 gpu 驱动，但是没有例程可以测试，请问该怎么测试 GPU？官方有没有提供测试例程还有 OpenGL ES 的 arm64 库？
