TRITON module support
The Kit-1 includes a DIMM144 connector for the TRITON module. The TRITON-UCB and TRITON-ECO only have this type of connector and therefore the Kit-1 is the only choice.
However, the TRITON-ETN, -LP and -XXS modules also contain the 2 x 100 pin SAMTEC connectors and for most applications the Kit-2 would be the best decision.
Using Compact Flash cards
The TRITON Development Kit-1 only supports the use of memory cards ('IDE mode'). If you want to use WLAN cards ('CF mode'), you will need Kit-2.
Development
The recommended host consists of:
| ix86 PC |
Linux 2.4 or later |
| cu, minicom |
or any other terminal program |
| tftp |
to upload files to TRITON |
| nfs |
to share files between host and TRITON |
| jffs2 support |
to create Flash ROM images for TRITON |
Programs are developed on the host and then uploaded to the TRITON module using TFTP via the Ethernet connector, or XModem and RS232 - though this is much slower.
Software tools are supplied (see TRITON FAQ: Tool chain)
