Cannot freeze into custom firmware

[muranyia]

I'm trying to freeze the driver into a custom circuitpython firmware by adding
FROZEN_MPY_DIRS += $(TOP)/../Adafruit_CircuitPython_Bundle/libraries/drivers/adafruit_mcp230xx
to mpconfigboard.mk. This works for other drivers, but for the mcp230xx I get:

make: *** No rule to make target '../../../Adafruit_CircuitPython_Bundle/libraries/drivers/adafruit_mcp230xx', needed by 'build-feather_m4_express/frozen_mpy'.

Have you tried adding the the repo to the frozen/ folder? Then you could do:

FROZEN_MPY_DIRS += $(TOP)/frozen/Adafruit_CircuitPython_MCP230xx
