I'm using the Linux port of SAM-BA (http://www.linux4sam.org/twiki/bin/view ... twareTools) on an Olimex SAM9-L9260 board with an AT91SAM9260 controller and NAND flash on it.
While erasing and flashing NAND works, the USB connection is terribly slow (9600 bps).
For this reason even flashing small memory images takes ages.
Unfortunately, I'm not able to change the speed of the serial USB device:
Code: Select all
$ stty -F /dev/ttyUSB0 speed 9600 baud; line = 0; min = 1; time = 5; ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke $ sudo stty -F /dev/ttyUSB0 speed 115200 9600 stty: /dev/ttyUSB0: unable to perform all requested operations
I know that SAM-BA also works using the RS232 serial port, but I would prefer to rather not use it since the serial console of the board is on the RS232 port as well.
- Is there a way to speed up the USB connection, so that flashing NAND doesn't take ages ?
- Did anyone have better success with alternative USB flashing tools ?
Like for example:
- Sam_I_Am (http://claymore.engineer.gvsu.edu/~ster ... index.html) or
- sam7utils (http://wiki.openpcd.org/wiki/Firmware#F ... _SAM-BA.29) ?
- If so, are they faster ?
