when i build target, the software shows the following message "Device is not supported by toolchain" what it means? screenshot: i24.photobucket.com/.../error.jpg can anyone help pls?
Do you have the C51 toolset installed? There are four different tool sets you can get for uVision (C51, C251, C166, and ARM). Each toolset supports devices in that particular family. So, if you installed the ARM tools, you won't have support for any 8051 devices (unless you install the C51 tools, too).
