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

Hi,
Thank you for your reply, it worked and we are able to test it.
one more issue we are facing if u can help it will be good.
display lcd is not working in the board, although we are creating it's corresponding gpio directory.

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"
* About half way down the list, update "Select the phy mask".

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.

No we use the RGMII2 interface extensively on our devkit and don't have any issues. The RMII2 interface has a pinmux conflict with the NAND memory, which is why it doesn't work for Rev1 silicon.
