I need to build a firmware for WROVER with ULAB module and have access to the external SPIRAM.
I've managed to flash the firmware with ULAB module, but i don't know how to build a firmware able to access the external ram
as the official GENERIC-SPIRAM : esp32spiram-idf3-20191220-v1.12.bin.

Any idea?

thanks

When you run the makefile (with the path set to the ulab module), you can specify which board you're targeting.

i.e.

Hi Jimmo, thanks for the prompt reply.
When i try to build with make board=generic_spiram i have the following error

make BOARD=GENERIC_SPIRAM
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
