The README had grown into one long page where the basic flashing workflow was buried between VIP, multi-programmer, ramdump, kickstart, WSL2 and raw sector guides. Keep only the generic material in the README and move each specialised workflow into its own file under docs/, linked from a new "Documentation" index. The moved text is unchanged apart from heading levels and two cross-references. Signed-off-by: Igor Opaniuk <igor.opaniuk@oss.qualcomm.com>

# Collect crash dump
|
|
|
|
When a Qualcomm target crashes or is forced into crash dump mode, the
|
|
bootloader re-enumerates the device over USB with Product ID `900e` and
|
|
offers memory segments for collection via the Sahara protocol.
|
|
|
|
A kernel crash can be triggered on the target with:
|
|
|
|
```bash
|
|
echo c > /proc/sysrq-trigger
|
|
```
|
|
|
|
Use `qdl ramdump` on the host to collect the dump:
|
|
|
|
```bash
|
|
qdl ramdump -o ./ramdump
|
|
```
|
|
|
|
Each offered memory segment is written to a separate file under
|
|
`./ramdump`. To collect only specific segments, pass a comma-separated
|
|
filter:
|
|
|
|
```bash
|
|
qdl ramdump -o ./ramdump OCIMEM,CODERAM
|
|
```
