DTS文件里边使能DSI0的节点,需要多大分辨率就配置多大,这样就可以远程登录桌面了。

RE: CM5使用U盘刷机失败
@Twsuts-0
你仔细看一下我们的那个脚本,实际上思路很简单,先dd一个img镜像(大于你的FS的大小),然后把这个镜像分为2个区(一个放boot,一个放FS),再然后把镜像挂载到系统,再把系统对应分区直接复制到镜像分区,然后做一些文件系统检查的工作即可。 -
RE: no usb-c charging
@Momo-0
At present, PD charging only supports charging when turned on, and does not currently support charging when turned off. The protocol only supports TYPEC PD format and does not support QC standards. So you need to use an adapter with TYPEC interfaces on both ends as shown in the following figure:

可以先删除boot/firmware里边的文件,然后再拷贝。注意删除前最好备份一下,否则错误的文件会导致系统无法正常启动。 -

RE: Constant noise from speakers?
@Ranomez
This machine is the latest version of V20, and I have understood the issue you have reported:- This noise is the bottom noise of the audio codec that is amplified by the power amplifier and output. In fact, the native bottom noise is very small, which can be confirmed by inserting headphones. It's only after being amplified by the amplifier that you can hear it near the ear at the speaker end.
- To avoid this common problem, the traditional approach is to only turn on the amplifier circuit when there is audio output, and then turn off the amplifier after the audio is played. This way, the normal sound output will cover the background noise, as shown in the driver code below:
static int es8316_mute(struct snd_soc_dai *dai, int mute, int direction) { struct snd_soc_component *component = dai->component; struct es8316_priv *es8316 = snd_soc_component_get_drvdata(component); es8316->muted = mute; if (mute) { es8316_enable_spk(es8316, false); msleep(100); snd_soc_component_write(component, ES8316_DAC_SET1_REG30, 0x20); } else { snd_soc_component_write(component, ES8316_DAC_SET1_REG30, 0x00); msleep(130); if (!es8316->hp_inserted) es8316_enable_spk(es8316, true); } return 0; }
- Your current operating method is to only turn on the amplifier without normal audio data output, which is equivalent to the amplifier only amplifying background noise data. So what the speaker hears is the amplified background noise. The current situation I have tested here is that the ear needs to be close to the speaker to hear, which cannot be heard in normal usage scenarios.
- Later, we will try to adjust the gain configuration of the amplifier at the driver end, hoping to reduce the amplitude of this noise, but it is unrealistic to completely eliminate it.

If you can open the back cover of the machine, please take a photo and send it out, I will confirm the version. -
RE: Constant noise from speakers?
@Ranomez
Can you confirm if your machine is V10 or V20 version? When did you probably purchase the machine?
