- Thu Nov 06, 2014 2:03 pm #2286 Hello,

Did anyone try compiling anything on SDK 0.9.2 that references these two functions?

They seem not to exist!

In SDK 0.9.1 they are declared in user_interface.h but in SKD 0.9.2 they are missing. When I declare them in user_interface.h of SDK 0.9.2 I get the same error while compiling.

Am I missing something here?

Regards,
Muris

Not deprecated, removed completely with a minor version bump. Wish i could change my APIs like that
New functions are called spi_flash_read, spi_flash_write, spi_flash_erase_sector.
This seems to work: https://github.com/igrr/atproto/blob/master/target/esp8266/config_store.c.

I recently found out how to use those new FLASH functions from the "user_esp_platform.c", but they didn't say that amount of memory we write/read from flash must be dividable by 4!!!

Probably it must be long-word aligned, this is generally the case for 32-bit CPUs.
