Couldn't write a littlefs data filesystem

[lugdunum-1964]

For a project I'm storing a web site on a littlefs data partition on the chip.
During make flash_fs I found two issues:

first:
esptool.py in ~/esp32/tools/esptool didn't exist, was called esptool without extension,
I created a symlink to solve.

second:
parse_arduino.pl created the the same command for FS_UPLOAD_COM as for UPLOAD_COM.
I traced that to line 150:
$fs_upload_com =~ s/(.+ --flash_size detect) .+/$1 \$(SPIFFS_START) \$(FS_IMAGE)/;

The flash size in platform.txt and boards.txt is always 2, 4, 8, or 16MB, so the search pattern 'detect' always failed. This maent running "make flash_fs" just flashed the code, and not the data.

Replacing the line by
$fs_upload_com =~ s/(.+ --flash_size \d+MB) .+/$1 \$(SPIFFS_START) \$(FS_IMAGE)/;
fixed the issue

Thanks for reporting. I missed testing for esp32. Fix coming soon

Regarding the first point above, did you run the get.py in the tools directory? That command creates the esptool sub directory

Regarding running get.py, I did run that.
Regarding the esp32, I'm using a AZdelivery ESP32 Dev Kit V4, which according to the manual should be treated as a regular esp32 dev kit, so board=esp32, chip=esp32.

I checked both boards.txt and platfom.txt in the esp32 directory (the latest pull from github) and none of the boards have a build.flash_size=detect, it's all 2,4,8 or 16MB. So the replacement regex wouldn't match any of these.

Fixed in latest commit now
