RE: 请问coolpi 4b 电源输入功率多大合适,有电流保护吗?
@night 机器TYPEC前端电源芯片耐压可以达到28V,极限可以到34V,所以你的适配器规格没有任何问题。
开发板的电源部分一直是我们设计最优先考虑的方向,所以前端第一级电源花了很多功夫,考虑到用户各种各样适配器的规格,最终选择目前国内少数几家真正能做车规级别电源方案的厂家。尽量保证前端电源稳定可靠。

RE: CM5支持5G模组吗?
@jugg
我觉得应该是你系统的ko和内核不匹配导致的,使用如下命令解压ko到系统,然后重启试试:sudo rm /lib/modules/* -R sudo tar -zxvf /boot/firmware/modules.tar.gz -C /lib/

RE: Coolpi CM5-Laptop 5G module design
@jugg
这个是RTL的驱动注册有问题,你可以加LOG信息在rtk的驱动里边跟踪一下,定位到具体哪里报异常。然后再想办法解决。 -
RE: Coolpi CM5-Laptop 5G module design
@jugg
这个要看具体的log信息,是驱动有冲突还是什么问题,你可以使用PCIE的网卡暂时规避这种问题,CM5的机器可以支持多种型号的PCIE+USB网卡。
这个模组目前是针对CM5的笔记本设计的,CM5-EVB暂时用不了。 -

Schematic design
Module Pin Definition
- Module pin layout,It can support PCIE interface or USB3.0 interface. We chose USB3.0 interface design, which is relatively easy to handle for compatibility and driver.
Signal connection
-
Schematic encapsulation definition, based on the PIN definition of the module.When connecting USB3.0 or PCIE signals, they should be crossed, with TX connected to processor RX and RX connected to processor TX.
-
Select the minimum GPIO method because the Coolpi CM5 laptop completely loses power during sleep, so it does not support module wake-up system. The GPIO connection is as follows:
-
The following table describes the signal list, which is mainly divided into power supply, USB3.0, SIM card, and control signal.

Power supply
The following figure shows a reference design for +5 V input power source based on an DC-DC
TMI3253SH. The typical output of the power supply is about 3.7 V and the maximum load current is 3A.
Power sequence
The turn-on scenario is illustrated in the following figure.
- tpower-on is time the interval between VCC and RESET_N HIGH level, which is a typically 33 ms. It is
measured when RESET_N is not pulled down by the host device. - tturn-on is the time interval between FULL_CARD_POWER_OFF# HIGH level and RFFE_VIO_1V8(an internal LDO output) HIGH level, which is typically 68 ms.
- tbooting is the time interval between RFFE_VIO_1V8 HIGH level and the USIM_VDD power-on.
Turn on the Module
It is recommended to use a host GPIO to control FULL_CARD_POWER_OFF#. A simple reference circuit
is illustrated in the following figure.
Turn off the Module
Pulling down the FULL_CARD_POWER_OFF# pin will turn off the module. The turn off
scenario is illustrated in the following figure.PCB design

RE: 接入笔记本电池
@jugg
如果是TI的库仑计,而且内核有驱动,正常DTS配置一下就可以了。如果是linux内核没有的库仑计型号,就需要自己加驱动,相对麻烦一点。
