JC 05:04 PM Software Development: RE: fw_printenv not working

Your config file looks reasonable. Though I'm not sure we've ever gotten the fw_printenv command working. I just tried to build the command in two different versions of u-boot and got a variety of compile errors. But in theory you can ... Jonathan Cormier

SW 10:14 AM Software Development: fw_printenv not working

Hi,
fw_printenv command in kernel is not working, for new kernel (4.14).Is there any configuration we have to do u-boot or kernel for this to work.
we are using your u-boot & kernel images only for this experiment for AM3352.
fw... Srinivasa Wunnimani

hi,
yes thanks for the reply, we shall create a new thread regarding that issue.
& Regarding the Ethernet ping issue:
without adding max-speed property, we are getting "Link is Up - 1Gbps/Full - flow control rx/tx".
that is 1Gb... Srinivasa Wunnimani

Could you provide more info? Why does your lcd need a gpio exported?
It may help to have a separate post to keep the two issues but its not required. Jonathan Cormier

In u-boot we added an environment setting to disable gigabit advertising for our makerboard version.
In som.c, you can remove the ifdef and it will always set disable_giga. Jonathan Cormier

The CONFIG_CPSW_SEARCH_PHY_MASK needs to be updated in the config file.
* Run "make menuconfig"
* Navigate to "ARM architecture"

SW 03:26 PM Software Development: RE: Ping is not working on MitySOM-335x Processor Card

Hi,
How can we change speed of the Ethernet link from "1Gbps/full" to "100Mbps/full" as in "Link is Up - 1Gbps/Full - flow control rx/tx" .
is it in driver code or dts file after kernel is bought up.

Hi,
Thanks for your reply , we tried all the changes you have suggested in uboot som.c and in kernel dts file as well.
We are not able to ping to any host system , mean to say ping is getting failed in uboot,while dhcp command is n... Srinivasa Wunnimani
