  • LPC2478 + External Flash TEA28F128J3

    Situation.....
    It is needed more than 512к flash for a code. Decided connected by 0х80000000 (CS0) TEA28F128J3 (high address on gnd). I try to program External Flash using Segger J-Flash ARM V4.00a, talks that can not get Flash ID .
    One hundred times checked up everything... it is all right....
    Decided to check... wrote a code piece for reading of ID, erase 0 sectors and records in leading addresses a few short - all works is a conclusion: the microcircuit of External Flash is connected right.
    I try again to program External Flash (Segger J-Flash ARM V4.00a, JLink) is an attempt of Target+Connect - and talks again, that can not read Flash ID.

    Looked levels - the feet of CE# and OE# behave strange . in place of levels 0 at an appeal to External Flash on them present approximately 2V. Such impression, that JLink is not able to program External Flash at this MCU?




    a problem is decided, excuse me, overlooked
