Dear Marek,
YOU DROPPED THE MAILING LIST AGAIN !! HOW MANY TIMES DO I HAVE TO TELL YOU TO KEEP IT CCED ?!
Even if I assign 0x1234 to MSC2 I am getting the same timeout problem.
Because 0x1234 is 16 bit bus ... dont you use 32bit bus to that card ?
Can you suggest me some other solution?
Is this problem because of static memory configuration?
Check the bus with a scope I guess, that should give you some ideas.
Where should I concentrate for the solution, whether in net/tftp.c file or in drivers/net/smc91111.c file?
You can enable debuging output in the smc91111 driver.
Kindly guide me to come out the problem.
Thanks and Regards Stephen Paulraj C

Hello Marek,
I am using a customize board which has PXA270 controller. SMCS LAN91C111Ii-NU is connected to the static memory 4 (nCS4).
I see, so it's not vpac270 bug.
I have defined following macro value in the include/configs/<myboard.h> file.
#define CONFIG_SYS_GPDR2_VAL 0x70DF3FFF GPIO 80 is configured as output
#define CONFIG_SYS_GPSR2_VAL 0x10010000 /*nCS4*/ GPIO 80 is set
You don't really need to configure these if you then set it to AF2.
#define CONFIG_SYS_GAFR2_U_VAL 0x1504A176 Alternate function 2 is selected for GPIO 80
#define CONFIG_SYS_MSC2_VAL 0x0000B884
Zylonite 300 uses value 0x3c for the SMC91111 in the corresponding part of MSCx register in original Marvell sources, Zylonite320 uses 0x123c ... maybe you should review the MSCx configuration here. For pxa27x, I guess it might be something like 0x123c too.
From the log below, it really seems the ethernet chip is choking.
Cheers
RT4 = 4 Variable Latency I/O (VLIO)
ROM4 Bus Width 0 = 32 Bits
RDF4 = 8
RDN4 = 8
RRR4 = 3

Ethernet controller is working fine. I can able to ping the machines connected to the network.
tftpboot command is also working fine, I can able to download the u-boot.bin to SDRAM.
But I have issue in downloading bigger files (zImage which is 2.5 MB) to the SDRAM. I am getting the following timeout messages and the download is not getting completed.

Please help me to come out of this issue.
