Added a delay between the bootloader hardware condition and device scan. #272

Closed ks156 closed 8 years ago

ks156 commented 8 years ago

New batch uses LPC11U24, and for some unknown reasons, the time needed for the USB enumeration is a bit bigger (few hundred millis), and then the update script fails to detect the LPC bootloader.

So... we do not know why this is needed. We just know that it is needed and that it fix the issue, right?

ks156 commented 8 years ago

This is needed because the LPC11U24 takes a bit more time to be detected by the kernel. This delay complements this one : https://github.com/nodesign/weio/blob/master/scripts/flash_lpc_fw.py#L104

There's not documentation or specs about the time needed by the bootloader to starts. This is empirical.
