Hello, I'm buying MCBSTR9 board soon, and I have a few newbie questions.
1. USB bootloader. Where can I get one, so I don't have to use ULINK all the time? (or maybe UART bootloader?)
2. I'm a bit confused about ethernet interface on this board. (I really don't know much about this, can someone explain please): What is this STE100P used for? www.keil.com/.../mcbstr9_to_ethernet.htm I thought that STR912FW44 has on-chip ethernet controller, and only two things more I need to make the ethernet capable device are RJ-45 jack and that small network transformer.... So what's this IC doing here? And where is transformer on this board? (if I wanted to build ethernet device some day, what else would I need, besides the STR912FW44 and RJ-45 jack?)
Thanks
The STE100P is a Ethernet transceiver. It is also known as a "Phy" since it provides the physical layer in the OSI network model. You need to have one of these (or something equivalent to it). Yes, the STR912 does have its own Ethernet controller, but you still need a Phy. Also, the transformer you speak of (otherwise known as "the magnetics") is built into the RJ-45 jack on the MCBSTR9 board.
I have put together simple Ethernet applications using this board and the TCP/IP stack that is a part of RL-ARM. I'm not smart enough to figure out how to write one on my own. It seems to work well...I would recommend using it....even if it is big bucks($$$).
Can't help you on the bootloader question. Best of luck,
R
