Nevim proc ale od nejake doby mi prestalo fungovat preprogramovani procesoru pomoci LPC2ISP s FTDI prevodnikem. Asi to ma neco spolecneho s tim, ze nyni nefungujou nove verze s FTDI
prevodnikem. Vytvoril jsem jednoduchy patch na resetovaci funkci.
Prosim aby to jeste nekdo jinej vyzkousel predtim nez se bude patch aplikovat do syslessu. Zaroven upozornuji, ze toto neni oficielni patch. LPC2ISP posledni doubou nejak zkomira.
