MW 09:11 AM Software Development: RE: Ethernet Interface to Micrel KSZ9021 PHY.: Hi Raja,
I don't think we've used this PHY with the MityARM-3359 here, but we have had problems strapping this device on other designs. The AM3359 has several pins pulled down (or up) after a power on reset. You should check Table 2... Michael Williamson

RV 03:31 PM Software Development: Ethernet Interface to Micrel KSZ9021 PHY.: Hi,
We are using MityARM SOM and MICREL KSZ9021RNI gigabit as PHY on it for Ethernet Interface.
We have configured ETH_RXD0, ETH_RXD1, ETH_RXD2, ETH_RXD3, ETH_RXCTL as pullup high on PHY reset to get mode[3 -0] to 0xF (RGMII Mode – ... Raja Vankam

AB 12:22 PM PCB Development: RE: Caution on MityARM SO-DIMM PCB Footprint: Mark,
Thank you for pointing out that lack of information. It has now been addressed and the design guide has been updated, October 1, 2012 1.2 version.
Thanks again,
Alex Alexander Block
MW 07:40 AM PCB Development: RE: Ethernet PHYs: Hi Mark,
I don't see a way around this at the moment. It does indeed look like you need to use the Gigabit Phy interface with the MityARM-3359 module.
Unfortunately, all of our initial use-cases involved Gigabit Ethernet requireme... Michael Williamson

MW 05:34 PM PCB Development: RE: Ethernet PHYs: Hi Mark,
You are correct about the PR1_MII* signals, according to this E2E post, sorry about that.

11:57 AM PCB Development: RE: Ethernet PHYs: Hi Mike,
The interfaces we definitely need out of the 335x are a 16 bit GPMC (to FPGA), 1 Ethernet (10/100 is fine), 2 USBs, 2 UARTs and 1 SPI. I'd like to keep the 16 bit LCD interface available but could use those pins for other th... Anonymous
MW 09:35 AM PCB Development: RE: Ethernet PHYs: What other peripherals are you trying to accommodate? At a glance it looks like the pin outs should support RMII0 on the LCD_DATAXX pins, but if you need the LCD interface. Can you list what peripherals you need?

08:49 AM PCB Development: Ethernet PHYs: Please correct me if I'm wrong, but it appears the pin-muxing configuration for the MityARM-335x SOM is forcing the use of an RGMII type interface for connecting up to Ethernet PHYs. For port 1, most of the interface pins are available ... Anonymous
08:26 AM PCB Development: Caution on MityARM SO-DIMM PCB Footprint: The PCB footprint found in section 6.5 of the MityARM-335x Carrier Board Design Guide can be misleading if you are not careful. This footprint (which is an exact copy of the footprint found on the JAE MM80-204B1-E1 data sheet) kind of i... Anonymous

MW 10:10 AM PCB Development: RE: MityARM standard-keyed vs. reverse-keyed SO-DIMM connector: We have not tested such a configuration, so I don't really know. If the electrical connections honor the spec, then the only immediate concerns I would have include:
# Clearance. The top side has a couple of components that are tall... Michael Williamson

AS 03:12 PM PCB Development: MityARM standard-keyed vs. reverse-keyed SO-DIMM connector: The MityARM design guide suggests an SO-DIMM connector with a standard keying. We have built our board with a reverse-key connector, is there any harm in installing the MityARM into a reverse-keyed connector with the OMAP facing downwar... Ali Asgar Sohanghpurwala

10:11 AM Software Development: RE: MityARM-335x Ethernet Communication: Found the problem. The problem was related to the errata on the Vitesse VSC8601 Ethernet phy used on the development board. The phy violates some RGMII interface clock specs if the RX clock skew in the phy is set to 0 (which it is foll... Anonymous

09:49 AM Software Development: MityARM-335x Ethernet Communication: I am trying to get the TI StarterWare Enet_Echo example to run on the MityARM-335x Development Kit. To accomplish this, I'm doing the following:
1. Use the the supplied SD card to boot the system and stay in u-boot (this initializes t... Anonymous

Tried that with no luck...
however I was looking through the lighttpd documentation and saw I forgot to build the dependencies.
I added "apt-get build-dep lighttpd" and then tried to build and it generated the shared libr... R D

SG 12:38 PM Software Development: RE: mod_fastcgi.so: Randy,
Could you give me a link to where you downloaded the lighttpd source? Also once you downloaded it, can you give me the exact steps you took to build it? It sounds like you're on the right track but there's just something simple... Scott Gerenser
RD 09:41 AM Software Development: RE: mod_fastcgi.so: Hi Mike,
I found out the version of the lighttpd based on one of the included shared libraries.
I have downloaded that version and successfully cross compiled it using arm-arago-linux-gnueabi-gcc
However, when compiling only the sta... R D

RD 10:57 AM Software Development: RE: mod_fastcgi.so: Hi Mike,
Should have mentioned Linux and Lighttpd are very new for me.
I had assumed I could just compile the lighttpd included in the ti-sdk-am335x-evm-05.03.02.00 and transfer it to the AM3359 module.
However, I do no know how to do... R D

MW 06:36 AM Software Development: RE: mod_fastcgi.so: So anyway, the mod-fastcgi.so should not require you to rebuild the kernel. You should be able to download it, "configure" it, and install it on your platform filesystem.

MW 12:54 PM Software Development: RE: mod_fastcgi.so: What filesystem are you using? You might be able to get it installed using opkg.

I'm trying to use fastcgi with the lighttpd web server. I have successfully create a simple example and changed lighttpd.conf file to include mod_fastcgi.
