Hi,
I have a problem when I connect P9.24 (ttyO1.TX) with P9.26 (ttyO1.RX),
If I send data on serial port like this : echo 1 /dev/ttyO1
And read data on serial port like this : cat /dev/ttyO1
The command output a lot of data indefinitely ... and

I found the examples in 'am335x_pru_package' on GitHub very useful, and was
able to get them working on a 3.8 kernel.
DDR access will have additional latency but 5.8us sounds high.
Is that for 1 LBBO instruction?

I am running ubuntu on BBB rev C and I have a USB disk attached. I am
having trouble accessing large files on the USB disk over sftp and ftp.
When I start a transfer it starts fine but after some minutes CPU is at
100% and the transfer slows to a crawl. I have tried different ftp servers
Do you have env ARCH=arm ?
or:
make ARCH=arm?

Check on linux-omap, Tony's been adding DM81xx support..

I think the problem with lack of mainline DM81xx support, is TI/etc never

Yup, a shame
I would believe this is because business reason :)

As I understand
USB 2.0 will cause 8000 interrupts in 1 seconds , an interrupt per 125us
while read / write will cause some spin lock , specially ,when your write .
And erase 1 nand block will cause several millisecond
so when you write the usb stick . you always get no useful spin lock wait ,

1) dm81xx only support syslink ti called ipc ver1.x
2) dra74x only support ipc version 3.x , compatible with linux kernel rpmsg
3)pci-e is nothing with Ti ipc
4) Ti implement ipu/hdvpss on their m4/m3 with BIOS/rtos ,this is depend on
the ipc version . and no opensource code

IPC should be pretty easily portable; which is also evident from the fact
that IPC 3.x supports tci6638,
