Topic: howto gain serial access to bricked ARV452CPW

The content of this topic has been archived on 30 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I have bricked an Arcadyan ARV452CPW while flashing the u-boot.bin. Now I only get the following message on the console connected to the serial port.

ROM VER: 1.0.3
CFG 01
Read EEPROMX
X

How can I proceed from here? I have looked into the forum discussions here, but I could not find any useful hint.


Thanks

Until now I could not find a datasheet of board nor of the cpu itself. Is somebody here who can tell me how to identify the signals boot_sel0, boot_sel1 and boot_sel2 to set the uart to cfg4?

It´s huge and I partly digged into it. I hoped to find there some link to a datasheet or somebody talking about the 10 pin header where the serial interface is located. What are the other pins? root_selxx?

thanks anyway

Frank

The discussion might have continued from here.
