More FAQ >>
1. MYS-SAM9G45 root directory capacity only shows 64MBQuestion:I'm using the MYS-SAM9G45 board under Linux. But found the root directory capacity is only 64MB when using the df -h command. So 256MB Nand Flash seems lost much space for using. How to solve the problem then?Answer:
Hello, that's because the much space of the MYS-SAM9G45 is as user space which has not been mounted. User may need to mount it himself and then it can be used. You can follow below ways:
1. Please use text editor to open the file "at91sam9g45ekes_demo_linux_nandflash.tcl" before the system auto-programming;
2. Go to the location roughly in the 84th line, the contents are as below:
"bootargs=mem=128M console=ttyS0,115200 mtdparts=atmel_nand:5M(bootstrap/uboot/kernel)ro,64M(rootfs),-(data) root=/dev/mtdblock1 rw rootfstype=jffs2" \
Please change 64M to 200M and note do not change to 256M as part of the space will be used for uboot and system.
"bootargs=mem=128M console=ttyS0,115200 mtdparts=atmel_nand:5M(bootstrap/uboot/kernel)ro,64M(rootfs),-(data) root=/dev/mtdblock1 rw rootfstype=jffs2" \
3. Re-programming
4. It will be as following if successful.
root@at91sam:~$ df -h
