PCMCIA-CS 3.2.5 with JFFS2

[G.Muruganandam]

Hello,

I have a board based on PowerPC 8541 with the following system details.

CPU                          : MPC8541
PCCardBus Controller : TI PCI PcCard bus controller 1410

U-boot version             : 1.1.2
Linux Kernel               : 2.4.20
PCMCIA-CS package  : 3.2.5
File system                : JFFS2
AMD Flash size          : 32 MB ( 30 MB used for JFFS2)


A SanDisk compact flash of size 256MB is connected to the CPU through the
TI's PC card bus controller. I have enabled the JFFS2 in the kernel, the root
file system is in the bootflash ( AMD ).

Issue:
====

if I use the one of following options to stop the PCMCIA service and power 
cycle
the board or reset the board, the compact flash is getting detected every time
when the system reboots next time.


1. cardctl eject
     /etc/rc.d/rc.pcmcia stop

2. System reboot using reboot command under linux prompt


If I either reset or power cycle the system without running above commands, 
the
compact flash is not getting detected during next linux booting process. 
This is due
to the reason that memory_cs is getting loaded instead of ide_cs module.

In other words , compact flash is not getting detected when the system is not
gracefully shutdown.

Also, I am not seeing this behavior when I download the ramdisk in to the 
main memory
and boot linux. In this case, the compact flash is getting detected every 
single time.

The issue happens only when the root file system is in the AMD flash(JFFS2).

I have provided below the screen shots for both working and non-working cases.

Pl let me know if you need more information and do let me know your 
suggestions to fix this issue.

Looking forward to hear from you.

Thanks
