Description: Write 1 to this file to update the ACHC microcontroller
|
|
firmware via the EzPort interface. For this the kernel
|
|
will load "achc.bin" via the firmware API (so usually
|
|
from /lib/firmware). The write will block until the FW
|
|
has either been flashed successfully or an error occured.
