## Modem Crash Log Patterns


## 修改 dump mode

tips: cmds for dump
```bash
# check dump mode
adb shell
cd /sys/kernel/dload
cat dload_mode

# change from offline to online
# 这样设置以后, 就能用QPST 抓 DDRCS0_0.bin 的full dump了.
adb reboot bootloader
fastboot oem ramdump online
fastboot reboot
```

## 导出 dump log


```bash
# pull ondevice crash log
# fulldump in rawdump.log file
adb pull /data/vendor/newdump/ramdump
# ssr dump
adb pull /data/vendor/ramdump
```


## 使用QCAP

### modem symbol

选择 .symbols-oem.zip 文件

### 平台
```bash
export N1_PATH_BUILD="/home/bytedance/disk4T/n1-w-rom-docker/n1-w-rom_0204/oak_amss/modem_proc/build"
```
在 `${N1_PATH_BUILD}/manifest.xml` 里查看平台信息.

### Selection
N1: 在 QCAP 中选择 Kanpali 平台, R1 KAANAPALI.LA.1.0.R1, modemsymbol 选择到 ms路径 `..symbols-oem\symbols-oem\modem_proc\build\ms`
