JC 05:04 PM MitySOM-335x (ARM Cortex-A8 Based Products) 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

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.

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

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.
