Hi all,<br>
I am new to U-boot environment.i am working on a custom board.<br>
which is having the 2MB of External RAM and 4 MB External Flash.<br>
i want to enable the fat file system support from U-boot.<br>
so that we should be able to copy some file from the device on which the file system is lying.<br>
i am trying SD RAM as device which will have the FAT32 file system.<br>
but currently i am not having that device so i want to apply this inteligence in External-RAM based image.<br>
and after it becomes succesfull i will try it for SD RAM.<br>
i am working in ARM 7 architecture.<br>
currently i have enabled the file system code with CFG_CMD_FAT macro<br>
and i am able to see the fatls,fatload,fatinfo commands on the serial prompt.<br>
<br>
so i have some queries as follows..<br>
1) What should i do so that i can use External RAM as an device??<br>
I mean how should i
treat External RAM as device in which i am copying the FAT file system
image.<br>
<br>
Because in fatload command first it calls the <br>
block_dev_desc_t *get_dev (char* ifname, int dev) and it returns pointer to appropriate device<br>
and i want to use External RAM as my device.<br>
(i am able to read and write the external RAM)<br>
if anyone is having any idea about it then please let me know<br>
<br>
Thanks and Regards<br>
