@jugg 再ubuntu通过apt source可以获取源码，放在debian下面编译安装，可能会有一些依赖包的问题，自己想办法解决一下。

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 designposted in PI CM5 Laptop
@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。 -

RM500Q-GL is a 5G NR/LTE-A/UMTS/HSPA+ wireless communication module with receive diversity. It
provides data connectivity on 5G NR SA and NSA, LTE-FDD, LTE-TDD, DC-HSDPA, HSPA+, HSDPA,
HSUPA and WCDMA networks with standard PCI Express M.2 interface.It supports embedded operating systems such as Windows, Linux and Android, and also provides GNSS
and voice functionality to meet specific application demands. -
The following table shows the frequency bands and GNSS type of RM500Q-GL module.
Mode RM500Q-GL 5G NR n1/n2/n3/n5/n7/n8/n12/n20/n25/n28/n38/n40/n41/n48/n66/n71/n77/n78/n79 LTE-FDD B1/B2/B3/B4/B5/B7/B8/B9/B12/B13/B14/B17/B18/B19/B20/B25/B26/B28/B29/B30/B32/B66/B71 LTE-TDD B34/B38/B39/B40/B41/B42/B43/B46/B48 WCDMA B1/B2/B3/B4/B5/B8/B19 GNSS GPS/GLONASS/BeiDou/Galileo
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.
Pin No Pin Name I/O Power Domain Description 2, 4, 70, 72, 74 VCC PI 3.135-4.4 V 3.7 V typical DC supply 3, 5, 11, 27, 33, 39, 45, 51, 57, 71, 73 GND Ground 7 USB_DP AI/AO USB 2.0 differential data bus (+) Require differential impedance of 90 Ω 9 USB_DM AI/AO USB 2.0 differential data bus (-) Require differential impedance of 90 Ω 29 USB_SS_TX_M AO USB 3.1 transmit data (-) Require differential impedance of 90 Ω 31 USB_SS_TX_P AO USB 3.1 transmit data (+) Require differential impedance of 90 Ω 35 USB_SS_RX_M AI USB 3.1 receive data (-) Require differential impedance of 90 Ω 37 USB_SS_RX_P AI USB 3.1 receive data (+) Require differential impedance of 90 Ω 36 USIM1_VDD PO Power supply for (U)SIM1 card Class B (3.0 V) 34 USIM1_DATA IO (U)SIM1 card data 1.8/3.0 V power domain 32 USIM1_CLK DO (U)SIM1 card clock 1.8/3.0 V power domain 30 USIM1_RST DO (U)SIM1 card reset 1.8/3.0 V power domain 66 USIM1_DET DI (U)SIM1 card insertion detection Internally pulled 6 FULL_CARD_POWER_OFF# DI Turn on/off of the module.

Internally pulled up to 1.8 V with a 100k Ω resistor 8 W_DISABLE1# DI Airplane mode control.Active LOW. 1.8/3.3 V power domain 10 LED_1# WWAN_LED# OD RF status indication LED It is an open drain and active LOW 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.

RE: 接入笔记本电池posted in Pi CM5
@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。 -
RE: 接入笔记本电池posted in Pi CM5
@jugg
你电池是自带库仑计的吗，如果是这样需要知道库仑计的型号，然后DTS增加驱动即可。单纯升级notebook的系统大概率用不了。一般笔记本电池内置的库仑计TI的型号会比较多。
