Good to know. I'm going to start with the Ipac 9302, unless you know |
| 12 |
of a better board. After I get (gentoo) embedded happy, I might |
| 13 |
spin a few boards... to ensure that the the hardware is truly |
| 14 |
accessible and get some AD and DA IO going for 4-20 ma signaling. |

Well often the EE does not realize all that is needed to bring the |
| 30 |
JTAG out to a full set of pins. SBC vendors usually do not like to |
| 31 |
make the JTAG port available to customers, for a variety of bidness |
| 32 |
reasons. JTAG device vendors are out to make a fast buck. Ever use |
| 33 |
Macraigor Systems? |

Maybe you just need some more (embedded) friends and some help? |
| 43 |
|
| 44 |
I do not mind publishing my work and documenting using JTAG devices |
| 45 |
with embedded(gentoo) Linux. I thing the Europa release of Eclipse |
| 46 |
will go a long way to bring embedded linux more mainstream. At the |
| 47 |
FreeScale Forum this summer, FreeScale did reveal all of their |
| 48 |
embedded linux capable processors would be migrating to the Eclipse |
| 49 |
Embedded platform (not sure exactly until they go public with the full |
| 50 |
details. |

Looking at the Zylin web site, I like their business model. However |
| 61 |
they look limited to arm7 (no thanks) tools and a arm7 on a FPGA. |
| 62 |
Interesting but not enough horsepower for my desires. I'm not much |
| 63 |
of a fan of Ecos. It's ok, but we usually use state-machine design, |
| 64 |
(if needed on a second embedded process for RT needs) and then use |
| 65 |
embedded linux, for the richness to application resources. |
| 66 |
|
| 67 |
|
| 68 |
Do you think Zylin would be interested in extending their JTAG |
| 69 |
solution to the Arm9 family? Got a contact at Zylin? |
| 70 |
|
| 71 |
Before I spend money on an SBC and JTAG I want to make sure they work |
| 72 |
together. I'm going to cc the contact address at Zylin... |
