Waveform from SPI flash dump

[ddB0515]

Hello

I have few panels would like to try with Glider but wanted to get original waveforms from SPI flash
For 1st test I have 11.3" 2400x1034 ED113TC1 and I've managed to get SPI flash dump (here is file: ED113TC1.BIN)
ED113TC1.BIN.zip

I did try to get it via wbf_flash_decompress but getting

$ ./wbf_flash_decompress ED113TC1.BIN out.wbf
Eink waveform flash decompressor
File size: 524560 bytes
Compressed length: 34 bytes
Warning: file size larger than expected.
Header version: 1527185408
Unsupported file version

So how to get Waveforms from panel SPI chip? Any suggestion or guidelines would be appreciated
Thanks

Sorry I saw the notification but forgot to reply. Generally for monochrome screens there is no need to run the flash decompressor. Eink only seems to compress the waveform on some selected color screens. The waveform is stored directly in the SPI flash with an offset. I wrote that in the README:

If your screen has a flash chip on it, it's also possible to extract the waveform from a flash dump:

dd if=somedump.bin of=waveform.wbf bs=1 skip=2182

So you basically just need to run dd to copy out the waveform, then you can use other tools to work with this wbf waveform.
