Hi

How do I  "setenv bootargs mem=64M console=ttyS0,115200 root=/dev/mtdblock0
rw rootfstype=jffs2" in barebox?

export seems not to work for me.

regards

Nataraj

the barebox shell is "sh" like, so use

bootargs="mem=64M console=ttyS0,115200 root=/dev/mtdblock0 rw rootfstype=jffs2"

BTW: barebox comes with a default environment for all board. Adopt it to
your needs.

cheers, Marc

... probably followed by

	export bootargs

as you asked for (C-Shell like) setenv, not set.

BTW, I recently saw a bug concerning export.  Exporting a variable
twice results in an error.  I havn't investigated it though.

Best regards
Uwe

Hi Marc

My board is at91sam9263. I am fully on Nand flash. Before i fully embark
onto barebox, may i have a few hints from you?

1. Can i do away with initial at91bootstrap.bin?
2. Using file jffs2 on Nand which takes at least 10 sec to mount, do you
suggest any substitute that barebox supports?
3. How stable is barebox now?

warm regards

Nataraj
