Hi and thank you for help,
When I send petaLinux by R232 and I use a simple command line as “ls” or “cd” I see that petaLinux is very very slow. For example, the command “ls” put 2 seconds to display the file system.
I am using a Virtex 4 with a Microblaze clocked at 100Mhz. petaLinux is built with a 2.6 kernel. On ‘OS’ part of ‘.mss’ file I write 66666667 on CORE_CLOCK_FREQ_HZ parameter.
I think the origin of my problem stems from that. What can I do for petaLinux get a better speed? I would like fix this petaLinux slowly problem before seeking something else.
Cordially,
Thierry.
Hello,
I have found out that it depends also on the tftp server I use.
If I install the normal "tftpd" from the debian archive I had the same
problems. Now I use the "atftpd" package (advanced TFTP server) and
there are no longer any difficulties. u-boot sends some "timeout" and
"blksize" information to the tftp server. The normal tftpd ignores this
but the atftpd server honors this (especially the timeout stuff).
Hope this helps,
Hans
