uOS на Uno32

[vak]

Наконец-то допинал перенос uOS на платы Uno32 и Max32.  Померял время переключения задач и время входа в обработчик прерывания - получилось соответственно 2.13 мксек и 0.90 мксек.  Вполне неплохо.

а конкретно какие чипы? на MSP430G2553 можно завести?

Не получается прошить плату. Указал в target.cfg путь до компилятора и avrdude из сборки mpide для chipkit - процесс завершается бесконечным таймаутом. Из пример blink из mpide прошивается нормально.
