AP6210 no answer by uart (h4) interface after hard reset. #2
Description
What steps will reproduce the problem?
1. Do a hard reset AP6210 chip or BCM2048, for example.
2. Try to load firmware (brcm_patchram_plus) using hardware uart (not usb)
interface.
To properly initialise chip's uart interface you must "twich" CTS line
(HIGH->LOW->HIGH) before sending any data to them.
It may be done by opening appropriate port, pause (some msec) and then close
port.
