JTAG-HS3 modify XMD -cable frequency: attempting faster downloads and communication


embP

Question

It does not appear that the 30MHz maximum speed for this device is operating, and or configured correctly when downloading an elf file

 

Ubuntu $ xmd

XMD% connect mb mdm -cable frequency 30000000

XMD% dow myFile.elf

 

the download time is identical whether frequency is set from a low number 125000 to a high number 30000000 

 

also attempted:

XMD% fpga_isconfigured -cable frequency 30000000

...

FPGA is configured

 

Is there an XMD command to show the "current" frequency?

Despite our assurances, it looks like this post got passed over again... apologies to embP and anyone else who ended up here looking for an answer.

On the off chance that this problem is still affecting you, or if this is affecting anyone else, please provide the version of tools being used (ISE 14.7, Vivado 2014.4, e.g.). We need this information to further investigate the problem.
