GRMON 4.1.0 issues

General - Software
1

Hello all,

We have detected an issue when updating GRMON evaluation to version 4.1.0 (or 4.1.0.1).
When we execute our ethernet initialization script we get the following error:

Device index: greth0
EDCL ip 192.168.220.4
EDCL mac 03:00:00:00:00:00
EDCL buffer size 16 kB
Device not found!

When trying to execute any program we also encounter an error:

grmon4> run
ERROR! JTAG data invalid! AHB access did not complete, returning bad data.!
Error occurred, disconnecting (308

Unknown failure!
Debug link has disconnected!

Note that with GRMON 4.0.7 this issues does not happen and the execution works as expected.

Edit: I added a format for the GRMON messages.

Edit 2: This happens on our custom platform (METASAT). On a simple noelvmp platform, it seems to work correctly.

Thanks for your help.

Best,
Marc

Hi Marc,

Which cores are included in your design?
Could you provide the output of info sys?
