вопрос в следующем: есть рабочий эмулятор, с нашими железяками на 5502 он работает без вопросов
попала в руки очередная железяка на 5409, эмулятор упорно не проходит тесты

-----[An error has occurred and this utility has aborted]--------------------
This error is generated by TI's USCIF driver.
The value is `-233' (0xffffff17).
The title is: `SC_ERR_PTH_BROKEN'.The explanation is:
An attempt to scan the JTAG scan-path has failed.
The target's JTAG scan-path appears to be broken
with a stuck-at-ones or stuck-at-zero fault.

sm510ctl
-tck (1-9)
-sld (0-1)
-pe (0-1)
и параметра [unify_linkdly] (3-5)
в различных вариантах ни к чему не привели, при том, что две других железки стабильно работают на 16 МГц (-tck 3 -sld 1 -pe 1)
длина хвостика POD-target меньше 10 см, испытуемая железка 100% исправна и с разводкой у ней вроде порядок, поскольку через этот же JTAG другой разработчик в другой конторе другим эмулятором ее шил
