Hiya,

There’s two different types of flash on the Q2686.

There’s the (configuration) flash - accessed by the adl_flhXXX() functions. According to the ADL User guide, there’s about 128k of flash; of which there can only be 2000 object identifiers; the maximum size of data pointed to by each object identifier is roughly 30k; and the flash can be erased/written around 100,000 times. This flash can be written and re-written without any special operations by the user

There’s also the ADL flash - used when downloading applications and is generally used for bulk data storage. This flash is accessed by the adl_adXXX() functions. This area can be resized by using one of the AT+WOPEN commands, and requires special care to erase/re-write.

Check out the FLASH and APPLICATION & DATA STORAGE sections of the ADL user guide for more info.

ciao, Dave
