[RFC] etc: Replaced PHY driver by a small dmx board fixup – Patchwork
This seems nuts to me. On 17 Dec, It is cheap, low power, available, and they give out the datasheets without an NDA. John Adair Enterpoint Ltd. Sign in Sign in Remember me Forgot username or password?
Understanding the etc PHY driver
Create free account Forgot password? The other problem with these companies is getting smallish numbers of chips is generally datasneet and difficult. Introduction to Microcontrollers Mike Silva.
Plus, all the source code is open as well, so who knows what secret registers that might reveal. Micrel has nothing gigabit on their website. An NDA might be more of a problem for the software; device driver source typically contains information about many of the PHY internal registers.
On Dec 17, 2: Anybody have any experience with it? Besides, I don’t want to reward such bad behavior by these chip companies. Can you imagine how hard it would be to design anything if every chip you used had NDAs attached to it? We didn’t think it was worth incorporating in development boards, or modules, if our customers couldn’t get the basic information.
axe(4) (Belkin F5D5055) problems
All claim to use about half the power, are much smaller, and don’t need the 1. We have had the same problem and partially why we have not as yet et11011c a phy module at gigabit available.
I mean, what could possibly be NDA-worthy in the datasheet for a 4 year old part that implements a technology GbE which is nearly a decade old? The schematic merely shows the pinout.
[RFC PATCH 01/17] et1011c: Replaced PHY driver by a small dm646x board fixup
I have found candidates from Marvell, Vitesse, and Broadcom. The pinout isn’t covered by the NDA, as that information is already published in schematics that you can download. I can only hope these companies stop being so snobbish as they get rapid volume turnoff in the current recession in their favoured consumer markets. I don’t see how this clashes with open source hardware though.
The fact that other users have been forced to redact pages of schematics tells me that this is a serious problem. It has 4 problems: For example, I found this schematic containing an 88E in less than a minute of searching: I am not a lawyer, and you should read the terms of the NDA very closely.
The problem is et0111c all of them require an NDA just to see the datasheet.
