Howdy,
Way back when (2.6.11 days) I built an image for a basix that does
MIDI and some audio analysis for a low-volume product. I haven't
needed to change anything for quite a while so I haven't been closely
tracking all of the software changes and the switch to OE. Now that
the basix is being EOLed, I need to bring up my app on a verdex pro.
To do MIDI (~31250bps) on the basix's FF and HW UARTS I had to modify
pxa.c to allow custom baud rates, turn off AFE on HWUART, and re-build
the kernel.
Then I could set up the port like this:
setserial /dev/ttyS3 divisor 29 spd_cust
stty -F /dev/ttyS3 speed 38400
and also enable the HWUART:
modprobe proc_gpio
echo AF1 out > /proc/gpio/GPIO48
echo AF1 in > /proc/gpio/GPIO49
echo AF1 in > /proc/gpio/GPIO50
echo AF1 out > /proc/gpio/GPIO51
for i in 42 43 44 45;do echo GPIO in > /proc/gpio/GPIO$i;done
Anyone know if these steps are still necessary in the newer kernel
builds for the verdex pro? It would be great to be able to use a
stock kernel if I can!
I've been searching the gumstix site and using google but have had a
hard time finding even simple info like which UARTs are available on
the audiostix2. Not even mentioned on the store's product page?!
Based on this picture:
http://pubs.gumstix.org/boards/AUDIOSTIX/PCB00012-R791/PCB00012-R791.bot.png
it seems that all 4 UARTS are brought out on audiostix2?
Is this the most current info on how the verdex pro's ports are used?
http://www.gumstix.net/Hardware/view/Expansion-boards/Basix-Connex-Verdex/Verdex-Pro-UARTs/112.html
It says that the BTUART is not exposed, but it seems the lines appear
on the audiostix2.
Is it possible to get to the serial console on FFUART with a tweener,
and then have MIDI on ST and BT UARTs on the audiostix?
Thanks for any pointers/info,
Darren
