Hi Pandu, |
| 77 |
|
| 78 |
ext3/4 is what is recommended by www.beagleboard.org/Robert |
| 79 |
Nelson/Angstrom Linux...but I have to confess that took this |
| 80 |
as simply "given". |
| 81 |
|
| 82 |
The other thing is: With sdcards one have to keep an eye on |
| 83 |
what part of the sdcard is written how often repeatedly, since |
| 84 |
sdcards tends to wear out. |
| 85 |
|
| 86 |
I read somewhere on the internet (dont remember where...sorry) that |
| 87 |
Samsung has offered code to the Linux kernel, which implements a |
| 88 |
special FS especially suitable and made for sdcards. |
| 89 |
|
| 90 |
But I dont know its name and whether it is already available in |
| 91 |
the kernel sources... |
| 92 |
|
| 93 |
Best regards, |
| 94 |
