Ми ако нямаш контрол кога усера ще слави шалтера - както моя случай ? Какво ще стане ако не се спази тая процедура - също неясно.... И какво значение има колко често се гаси и пуска тока - що пък точно 5 минути е толкова специално време ??? Айде, моля ви се, подксжете нещоо

Колегата е имал случай на едни изпитания как чипа както си е бачкал нормално и цитирам : "Спря да работи, просто умря..."

И на въпроса защо 5 минути?!? Ами това звучи толкова несериозно, все едно сме във времената на ТНТМ.

Caution – The Stellaris Flash memory array has ECC which uses a test port into the Flash memory to
continually scan the array for ECC errors and to correct any that are detected. This operation is
transparent to the microcontroller. The BISTmust scan the entire memory array occasionally to ensure
integrity, taking about five minutes to do so. In systems where the microcontroller is frequently powered
for less than five minutes, power should be removed from the microcontroller in a controlled manner
to ensure proper operation. This controlled manner can either be through entering Hibernation mode
or software can request permission to power down the part using the USDREQ bit in the Flash Control
(FCTL) register and wait to receive an acknowledge from the USDACK bit prior to removing power. If
the microcontroller is powered down using this controlled method, the BIST engine keeps track of
where it was in the memory array and it always scans the complete array after any aggregate of five
minutes powered-on, regardless of the number of intervening power cycles. If the microcontroller is
powered down before five minutes of being powered up, BIST starts again from wherever it left off
before the last controlled power-down or from 0 if there never was a controlled power down. An
occasional short power down is not a concern, but the microcontroller should not always be powered
down frequently in an uncontrolled manner. The microcontroller can be power-cycled as frequently
as necessary if it is powered-down in a controlled manner.

фрискейл ползваха лиценз на SST за техните контролери и затова май се усукваха около атмел.
не знам как са решили проблема накрая.
