Inte The problem I am facing are two : I am not sure whether my flash read/write routines are working properly .(cfi_cmdset_0002.c routines ) I am able to detect my flash and do MTD partions too on the flash .But I cannot see that in my dev directory .I mean I should see something like /dev/mtd0 ...etc . As I want to mount JFFS2 and I am not sure of whether i can mount any Filesystem without seeing it in /dev directory . Is there way wherein I can invoke mtd->write/mtd/-> read routines so that I can be sure that my CFI driver is working fine ? these routines are mapped to amdstd_read/write routines in cfi_cmdset_0002 routine . mtd->read =3D cfi_amdstd_read; mtd->write =3D cfi_amdstd_write; Here is my dump ################################################################ LSP Revision 1 Starting kswapd Disabling the Out Of Memory Killer JFFS2 version 2.1.

Can anyone help me in this naive problem ?

I am using k 2.4.= x based on ppc8245 based .I have a 8MB flash mapped to adress -0xff800000 .= with 4 interleaved AMD flash devices each of size 2Mib .
Inte

The problem I am facing are two :
I am not sure whether my flash read/wr= ite routines are working properly .(cfi_cmdset_0002.c routines )

I a= m able to detect my flash and do MTD partions too on the flash .But I canno= t see that in my=20
dev directory .I mean I should see something like /dev/mtd0 ...etc .
As I want to mount JFFS2 and I am not sure of whether i can mount any = Filesystem without seeing it in /dev directory .

Is there way wherei= n I can invoke mtd->write/mtd/->
read routines so that I can be sure that my CFI driver is working fine = ?
these routines are mapped to amdstd_read/write routines = in cfi_cmdset_0002 routine .
 mtd->read =3D cfi_amdstd_read;
=  mtd->write =3D cfi_amdstd_write;

Here is my dump
