Linux/AM3352: TFTP in U-boot from 2013.01

Part Number: AM3352

Tool/software: Linux

Hi,

We have one product based on AM3352 where NAND is default boot and first time we are using Ethernet/TFTP to flash NAND. We are observing issue from long time that Ethernet data rate is very slow in Uboot. Ethernet phy is in MII mode and also we have verified data rate with UBoot 2016.01 and we are getting almost 20 times higher throughput.

It is taking almost 25 minutes to flash One product and in production perspective it is very long. Also, as product is in market from last 3-4 years we can't change latest Uboot.

So, How to optimize it to increase data rate?

Best Regards
