In this case someone, who will need second USB but don't cares much about number of SPI interfaces, may sacrifice one SPI. </p> http://forums.leaflabs.com/topic.php?id=1508&page=2#post-10261 Wed, 18 Apr 2012 02:20:22 +0000 mabl 10261@http://forums.leaflabs.com/ <p>@siy, thx for the hint. I've not looked into USB that much. It seems this loss will have no impact on me. </p> http://forums.leaflabs.com/topic.php?id=1508&page=2#post-10260 Wed, 18 Apr 2012 02:12:01 +0000 siy 10260@http://forums.leaflabs.com/ <p>@mabl, it's not about host USB support, it's about second on-chip USB controller which supports high speed USB (with external PHY, only full-speed without external PHY). Both USB controllers in F4 support host/OTG, so in fact the loss is not very important, from my point of view. </p> http://forums.leaflabs.com/topic.php?id=1508&page=2#post-10257 Wed, 18 Apr 2012 01:38:39 +0000 mabl 10257@http://forums.leaflabs.com/ <p>Hi Olimex,</p> <p>thanks for the update! I'm definitely looking forward to both boards. Regarding the feature loss through Ethernet - I guess it cannot be helped, everybody has to find his own trade-off. Personally, I don't mind not having Host Support USB.</p> <p>Let the schematics come :-) </p> http://forums.leaflabs.com/topic.php?id=1508&page=2#post-10232 Tue, 17 Apr 2012 08:24:35 +0000 olimexino 10232@http://forums.leaflabs.com/ <p>just to update you: STM32-H407 routing is complete and we run the prototypes.<br /> the STM32-E407 development started and I will upload some preliminary schematics and would love to hear your comments.</p> <p>on first sight we have to forget about the HS USB as it eats the SPIs which we could use for the SD card and UEXT :(<br /> also Arduino platform on E407 should be shared with the external memory bus, i.e. you have either Arduino shield either external memory bus but not both at same time. </p> http://forums.leaflabs.com/topic.php?id=1508&page=2#post-10055 Mon, 02 Apr 2012 00:01:07 +0000 olimexino 10055@http://forums.leaflabs.com/ <p>It's too early to predict how the Ethernet will be routed, it's 100MBit Ethernet and we will route it for best signal integrity at first place </p> http://forums.leaflabs.com/topic.php?id=1508&page=2#post-10049 Sun, 01 Apr 2012 01:28:44 +0000 mabl 10049@http://forums.leaflabs.com/ <p>@olimexino</p> <p>I'd still favor the dedicated Ethernet board (no high speed signals over pins) - but I guess I'll have to live with what you provide ;-)</p> <p>Having a 407 board with ethernet and a lot of free IOs which are not used by onboard peripherals is really a dream come true - and even open source!</p> <p>Oh, and if there is an ethernet shield, could you build it in a way which has the ethernet port on the same level as the rest of the ports (as proposed in one of you blog comments) - this would be important for casing. </p>
