spiffs dump not working: error, downloading from spiffs #2982
Description
Describe the bug
spiffs dump is not working for traces that where generated using HF_14ASNIFF
I get the following error:
[usb] pm3 --> mem spiffs dump -s hf_14asniff.trace
[=] downloading 20162 bytes from `hf_14asniff.trace` (spiffs)
[-] error, downloading from spiffs
I can rename, delete, copy the file, but I can't view/dump it.
[usb] pm3 --> mem spiffs rename -s hf_14asniff.trace -d test.txt
[=] Done!
[?] Hint: Try `mem spiffs tree` to verify
[usb] pm3 --> mem spiffs tree
[=] --- Flash Memory tree (SPIFFS) -----------------
[#] [0001] 20162 B |-- test.txt
[usb] pm3 --> mem spiffs dump -s test.txt
[=] downloading 20162 bytes from `test.txt` (spiffs)
[-] error, downloading from spiffs
To Reproduce
Steps to reproduce the behavior:
- Load HF_14ASNIFF into standalone mode
- Sniff a mifare 1k
- Dump the file generated by HF_14ASNIFF
- See error: [-] error, downloading from spiffs
Expected behavior
File should download successfully.
Note: doing a spiffs test and downloading the test file works fine.
