[microblaze-uclinux] [microblaze-uclinux] U-boot can’t download “image.ub”

[Thierry BESSIERE <t.bessiere@xxxxxxxxxxxxxxxxxxxxx>]

Hi,

 

 

I would like download “image.ub” with a TFTP server but u-boot can’t download this file. Here is what I have in the hyper terminal:

 

_______________________________________________________

I use these command lines before starting the download:

_______________________________________________________

setenv serverip 192.168.0.71

setenv ipaddr 192.168.0.10

setenv bootfile image.ub

My questions ar the next :

 

1] Should I validate an option in menuconfig for the TFTP protocol?

 

2] On EDK, I must modify the parameters of EMAC?

 

3] PetaLinux is very slow on the FPGA, The lost packets can be the consequence of this?

 

Best regards.
