java.lang.NumberFormatException: For input string: ""

I get the following error trying to upload using this plugin:

Any clues valued.

I found the problem.

It happens when ./Library/Arduino15/packages/esp32/hardware/esp32/1.0.1/tools/partitions/default.csv contains this:

# Note: if you change the phy_init or app partition offset, make sure to change the offset in Kconfig.projbuild
nvs,      data, nvs,     0x9000,  0x6000,
phy_init, data, phy,     0xf000,  0x1000,
factory,  app,  factory, 0x10000, 1M,
storage,  data, spiffs,  ,        0xF0000,

Looks like the partition parsing code in this utility can't handle that partition structure for some reason.

@bootrino , first of all, huge fan of your work! especially with the esp32 a2dp source project! Now let me ask, did you find a solution for this tool with the modified partition? if no, there is any other similar tool available! Thank you

[Nathan-ma]

@bootrino . Well I just returned the lib its original content, use the tool and its working perfectly! Ty!

[bootrino]

@DarvosBR thanks for the kind words. I fixed it in the end by modifying the esp32 partition csv file - I suspect the problem is this utility cannot parse the line that says "1M" but I never bothered digging any deeper.

Could it be happening when the offset is empty?

[ghost]

I can confirm it does work when the offset is not blank. I used this command to convert the partition table with blank offset values to a bin: python gen_esp32part.py input_partitions.csv binary_partitions.bin

And then verify the bin file just created with the command above: python gen_esp32part.py binary_partitions.bin

And jsut like that it will print the computed offsets in console for you. You can then replace the csv file with the new values computed.

Guys I found the solution, at least in my case, by using mkspiffs tool provided by espressif, I made a new partition csv but in order to use the mkspiffs to upload the WAV file I made a batch script to run the mkspiffs with the memory locations I need.
