Re: почему не видит флешь? (D-Link 2640U)

аналогичная ситуация.
если поставить ключ noerase то виснет не на очистке а на одной и той же строке выполнив пару десятков строк .
cpu компа загружено на 100% а не движется
если прервать и попробовать рестор - в рестор пишутся все ноли, даже в те ячейки где было что прошито

Re: почему не видит флешь? (D-Link 2640U)

угу - mx29lv320cbt через jtag не определялась - принудительная устfновка /fc:** приводила к чтению только нулей...
Поменял на s29gl032m90tp - перепрошил через программатор - заработало и через jtag нормально всё читаться стало без всяких /fc:**
