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>

# Reading and writing raw binaries
|
|
|
|
In addition to flashing builds using their XML-based descriptions, QDL supports
|
|
reading and writing binaries directly.
|
|
|
|
```bash
|
|
qdl prog_firehose_ddr.elf [read | write] [address specifier] <binary>...
|
|
qdl prog_firehose_ddr.elf [erase | sha256] [address specifier]...
|
|
```
|
|
|
|
`erase` wipes the addressed region and `sha256` prints the SHA256 digest the
|
|
device computes over it, which is a quick way to verify a write. Multiple
|
|
read, write, erase and sha256 commands can be specified at once. The
|
|
***address specifier*** can take the forms:
|
|
|
|
- N - single number, specifies the physical partition number N, starting at
|
|
sector 0. To read data, the number of sectors must be specified explicitly
|
|
using the N/S+L form.
|
|
|
|
- N/S - two numbers, specifies the physical partition number N and the start
|
|
sector S. To read data, the number of sectors must be specified explicitly
|
|
using the N/S+L form.
|
|
|
|
- N/S+L - three numbers, specifies the physical partition number N, the start
|
|
sector S and the number of sectors L, that ***binary*** should be written to,
|
|
or which should be read into ***binary***.
|
|
|
|
- partition name - a string, will match against partition names across the GPT
|
|
partition tables on all physical partitions.
|
|
|
|
- N/partition_name - a number followed by a string, will match against
|
|
partition names of the GPT partition table in the specified physical
|
|
partition N.
