Lots of users want to use Remote Tools using ActiveSync, but the connection always fails. Why ?
Remote Tools launched from Platform Builder 6.0 are using platman (Platform Manager) over ActiveSync to connect your device, when platman starts, it asks Windows CE to return the processor type, through a KernelIoControl, to download the right binary file to the device (client side of the tool). In the case of the ARM processor, Platform Manager do not seem to identify correctly the ARMV4i processor type, but identify ARMv4 instead. Therefore the tool cannot copy the right files to your device. The files used by the remote tools are located in C:\Program Files\Common Files\Microsoft Shared\Windows CE Tools\Platman\target\wce600\. Each sub folders contains the binary version for a specific processor familly (x86, ARMV4i, ....)
As there is no ARMv4 subdirectory, platform manager cannot copy the right file to the platform. The workaround to solve this issue is to duplicate your ARMV4I folder to ARMV4 one, and then, TADAAAA, it works !
