RM500U-CNV Jeson Orin Nano PECI模式无法拨号

MichaelYoung · 2025 年5 月 6 日 13:06

RM500U-CNV 在Jeson Orin Nano使用PCIE接口时，无法拨号，无法打开/dev/stty_nr31；相关信息如下：

模块模式确认以设置为0
AT+QCFG=“pcie/mode”

+QCFG: “pcie/mode”,0

OK

sprd_pcie版本V1.1.8，Makefile如下：

怀疑RM500U在重启。
要结合RM500U的内核日志来分析的。

MichaelYoung · 2025 年5 月 12 日 10:08

我切换到USB模式是正常的，可以正常拨号上网。 RM500的日志怎么抓？需要什么工具？可以发我一下吗？

BiaoWang-Q · 2025 年5 月 12 日 10:09

接出模块的debug串口，同时抓模块的debug 日志。

MichaelYoung · 2025 年5 月 14 日 01:38

抓了一份QLog日志，看是否能分析出问题， Debug口的硬件还在处理，稍后会抓出来.

PCIe枚举不需要QLog.
PCIe 对开机时序有要求。

MichaelYoung · 2025 年5 月 14 日 03:40

现在开启时序为：
Boot层同时打开P4V2和拉低5G_nRESET(RESET#拉高)，在系统起来是拉高5G_ON_OFF.

请问时序还有什么问题吗？需要注意和修改哪些地方吗？

MichaelYoung · 2025 年5 月 14 日 03:46

抓包时用了下面几个命令抓dump
root@cqh6:~/qlog_new# busybox microcom /dev/ttyUSB2
at+qcfg=“aprstlevel”,0
OK
at+qcfg=“modemrstlevel”,0
OK
at+qcfg=“dbgctl”,0
OK
at+qtest=“dump”,1

现在模块要如何恢复？（现在系统开机30多秒后USB断开了，也不会重启了）

MichaelYoung · 2025 年5 月 16 日 02:56

抓取的Debug口日志及dmesg日志，请帮忙看下是哪里问题

BiaoWang-Q · 2025 年5 月 16 日 08:18

log 里能看到模组是pcie ep mode了，且模块拉了pcie_wake.
没有看到主控拉pcie_rst.
另外，日志看到模块两次开机，模块是否有重启。

MichaelYoung · 2025 年5 月 18 日 08:53

我们安装文档要求调整时序图后，故障和之前一样，下图是示波器抓的PCIE_nWake和PCIE_nRST的波形。

附上内核日志如下：日志中tegra194-pcie 140c0000.pcie为对应PCIE接口日志，lte开头的打印信息就是对应的io口的控制情况
MobaXterm_192.168.55.1nvidia_20250517_220715.txt (133.1 KB)

从现象级上次抓的dump信息看，模块是一只在重启的，dump信息显示模块内核崩溃。

BiaoWang-Q · 2025 年5 月 18 日 09:04

MichaelYoung · 2025 年5 月 19 日 06:25

你标注的位置是在boot层， boot层RESET#没有释放，模块还是处在未开机状态。到了内核层才开机的，也就图中第一次PCIE_nWake的前几秒，才释放的RESET#。图总一格是20S。我理解第一次PCIE_nWake下降沿就是模块开机完成后拉的，我们在500ms左右释放PCIE_nRST了，但是模块还是持续了1S的低电平。后续都是模块在重启，我不理解为什么为重启（抓dump是模块内核崩溃）。也不理解为什么我们释放PCI_nRST没起作用。

BiaoWang-Q · 2025 年5 月 19 日 10:42

我现在能给的一个建议是：

如果uboot（bootloader）里有PCIe 驱动可以拿掉；
将模组的上电放在uboot 里完成（太早或者太晚都不行，和RC一起开机太早了，进了kernel再开机太晚了，得改pcie 控制器的程序），一般能使用这个5G模块。
