AM35127EVM, u-boot netconsole very slow

Antti Mauranen

Other Parts Discussed in Thread: AM3517

Hello,

I have been able to get netconsole to work with AM3517EVM/u-boot. Everything works but the console traffic is extremely slow.

I have set CONFIG_NETCONSOLE in am3517_evm.h and made the triggs on u-boot command line (setenv stdin nc; ...).

At PC end I use u-boot tool ./tools/netconsole 192.168.2.nnn and I get the u-boot command line at PC and can receive u-boot command line messages and send commands to u-boot.

But it is SLOOOOWWWW. All other network traffic is okay (e.g. loading uImage using u-boot).

Can anayone give some advice how to get more speed to netconsole.

u-boot version is u-boot-2010.06 (-psp04.02.00.07-r1).

Yours truly Antti

Hi,

I have got the same problem with DM8148 EVM. Wireshark shows me that in most cases only 16 bytes transferred at a time. For some cases it's only symbol in a packet. It would be nice if anyone has tried to enable the u-boot netconsole in the OMAP or DAVINCI boards.

I use EZSDK-5_05_02_00.

Any inputs are appreciated.

Thanks in advance,

Andrei

Hi,

It seems that the patch solves the problem. Ignore changes in ti8148_evm.h except these three lines:

#define CONFIG_NET_MULTI
#define CONFIG_NETCONSOLE
#define CONFIG_NETCONSOLE_PERSIST_ETH

they need to be added to u-boot section.

Cheers,
