I just bought Lilygo TPCIE sim7600HG that comes with 16MB flash. i have searched github and the net, and tried some of the tips but to my frustration, they didnt work. Any idea how to at least get 8MB for app0, 4MB for app1, and 2MB for SPIFFS.
Take a look at the following tutorial. It might help:
Found a solution, added these lines into …/board.txt, under esp32wrover board.
esp32wrover.menu.PartitionScheme.large_spiffs=Large SPIFFS (4.5MB APP/OTA/6.93MB SPIFFS)
created a new file ../large_spiffs_16MB.csv to reflect the above partition.
