Build firmware for external spiram

[davidbogatec]

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.

Code: Select all

make BOARD=GENERIC_SPIRAM ..other args..

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.
