[Openec] Ladies and Gents, we have a "brick with a monitor"

[Frieder Ferlemann]

Hi all,

the UART works now (sort of, see below). And openec now has kind of a monitor.

It allows to:

m - set address (4 digits denote xdata area, 2 digits 8051 data/SFR)
<return> - output content of address
+ - increment address and output content of address
- - increment address and output content of address
= - set contents of address
d - dump 8051 data and SFR space
g - dump xdata SFR registers (ec-dump.fth like)
G - detailled GPIO settings
s - switch off dump of the state-machines
S - switch on dump of the state-machines
? - very short help


There are some restrictions though:

- the UART RX is not working here if WLAN is not powered.
  RX/BAT_LO (CN24,3 CON2,45) seems clamped at about 2V
  if WLAN is powered off.
  Is that known and is CON2,45 within absolute maximum ratings?

- openec currently needs an inter character delay of 10ms
  (there'll be interrupt driven uart routines which will
  fix this)

- the ec-dump.fth like dump locks near the output of the
  content of 0xff50.


With the monitor it might be possible to power up the XO?


Greetings,

Frieder
