- Hi Everyone,
Merging in the changes from the tag (mitysom_AM335XPSP_04.06.00.07) worked for us to limit the ethernet speeds for the phy.
I removed the phy fixup function that was being called.
To reduce the speeds I modified the phy...

- Looking at my JCI kernel branch it does show that it was before we added the micrel phy support. You mentioned we gave you a more updated version with micrel support?
Do you have the following commits in your kernel tree? If so then ... - TE 12:10 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: KSZ9031 phy support for the 3.2 kernel
- I haven't tried you're suggestions yet. I will be able to this afternoon.
The kernel source we're using is much further back on the development tree, here's my dmesg output when I boot.

Here are some u-boot patches to disable gigabit in u-boot. This won't affect linux as you've noticed.

Thanks for the info. Easy enough fix!!
Much Appreciated!

Those warnings are caused by the uboot environment trying to read external environment setup scripts from the SD card, these scripts aren't present so you get that warning. This feature really was never used and shouldn't of bee... - Hello,
I am trying to figure out a couple of errors that occur during or right after pre-boot.

Glad to hear that worked!

- Dan,
Thanks for the reply. I am able to better control them using an external weak pull down circuit on power up, which gives a determinate state (Low) during boot.
Thanks again for the great ideas.

- Hi Greg,
Actually this was the page I referenced while I was working on u-boot. In the page, two solutions are suggested. The first one is the _bootdsp_ command which only works for _COFF_ binaries. Being Achilles' heel of the solution,... - GG 10:15 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: MityDSP boot problem
- Hi Caner,
Have you looked at our wiki page ([[DSP_Quick_Start|DSP Programming Quick Start]]) for launching the DSP without utilizing the ARM? If I am understanding your end goal this may be helpful to you.
Thanks,

- Hi,
We're working on a DSP software on MityDSP_OMAP-L138 board without BIOS and we do not intend to use ARM side in near future. We use COFF libraries whose ELF versions do not exist, thus we are unable to flash the DSP directly appylin... - MK 03:25 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: Accessing git repositories when behind firewall
I found a good solution which might be worthwhile sharing :)
