SwiftModule-OM achieves low-current suspend Windows CE
Obviously if you’re making a handheld device, boot time can be an issue. With our OMAP3530 based SwiftModule-OM, we’re seeing boot times in the region of 15 – 20 seconds. There are various things that can be done to reduce this, such as reducing the image size and using BinFS.
However, for many applications, the availability of Suspend and Resume support is critical. Unfortunately this is not available as a standard feature of the TI/BSquare BSP, but I’m pleased to say it’s now up and running our platform. Obviously a system in Suspend does not have the power switched off, and there will be some current flow. We are currently seeing 5.5ma (deep sleep), but in many situations, this is a small price to pay for the 120msec for full resume!
We expect to achieve further reductions in the deep sleep current.
