This is the BSP for Cogent Computer System's CSB337 and updated for CSB637, single board computers using the Atmel AT91RM9200 CPU. The differences in the board are very slight but important:

This is the BSP for Cogent Computer System's KIT637_V6. It implements an updated version of the CSB337 board with a number of optional peripherals.

This KIT is implemented by CSB637 single board computer using the Atmel AT91RM9200 CPU and the CSB937 target main board. It uses an Optrex LCD (T-51750AA, 640x480) and Touchscreen (not supported in this BSP). The IDE and USB (host and device) interfaces are also not supported. The SD and Compact Flash cards drivers are still under development.

The differences in the CSB637 single board computer are very slight but important:
