LAN95 (smsc95xx) causing data corruption

ciaran_lequeux — Fri, 03 May 2024 13:10:29 GMT

Hi,

I have a custom board with imx6 dual lite, i'm on linux.

I have a problem with data corruption in ftp download.

For my tests, in bash, i download, check md5sum and loop...

With direct network connection, i download from ftp à big file (1GB), 100% OK of all time

Now with usb ethernet adapter (LAN95), (i dissabled turbo mode, otherwise it crash)

With a 1GB file FTP : KO 100% of time
With a 60Mb file FTP : KO 1 / 10 of time
With 1GB file with SCP : KO 1 / 5 of time

Did you have any idea why isn't working properly ?

Hi,

Thank you for your interest in NXP Semiconductor products,

Do the connections advise the same capabilities?

Could you try this setting?

I could also watch this instability here,

Have you worked with other adapters?

Regards

Hi,

Thanks you, but on his thread he says it's ok LAN to LAN, his command not work wih me and i'm LAN to LAN.

It's a ctusom board and i can't connect other adapters

I've already test with this parameters from uboot : [U-Boot] [PATCH] smsc95xx: Fetch whole burst with 1 URB, avoid framing errors (kernel.org)

Without success
