доброго времени суток.

имею железки: sm510, и таргет с vc5509a. композер 3.1

вопрос такой:

эмулятор както интересно подглюкивает, т.е.

xdsprobe -r,

потом при первом (после -r) запуске xdsprobe -i -- тест проходит либо на 100%, либо 99,8%(см.ниже)

при повторном запуске xdsprobe -i приводит к появлению ошибки -270 (SC_ERR_SCN_LENGTH_CONTROL)

-----[An error has occurred and this utility has aborted]-------------

This error is generated by TI's USCIF driver.

The value is `-270' (0xfffffef2).
The title is: `SC_ERR_SCN_LENGTH_CONTROL'.

The explanation is:
The length of the scan is too large for the emulators controller.


манипуляции с разными кабелями от пода к таргету ни к чему не привели, всякие -tck, -sld, и т.д. - тоже не помогают
еще... xdsprobe -y -- без проблем проходит всегда
xdsprobe -g [data] -c -- без ошибок с разными данными, но только один раз после -r.

на другом таргете (с таким же процом) таже фигня, только почемуто в первом запуске xdsprobe -i длина IR instruction scan-path length is 6 bits. но тест проходит...

куда смотреть?..спасибо)
