    Да я жесткого ступил паяв минус к минуса, но в итоге сделал нормально: припаял диод плюсом (анодом) к земле RF-платы, а на катод диода кинул провод от резюка (которые перед дебагом идет - чтобы на полную яркость светил), оранжевый диод вообще классно выглядит, намного лучше чем синий.

    RichY,
    Thanks.
    So I connected the signal CE coming from southbridge to R4 resistor (the end which is closer to the chip) and measured the R7 and R8 (the sides which are toward the chip). Unfortunately they both show 1.8V output that does not change at all like this:

    NewFile3.png
    bottom - SB CE signal, top signal measured from R7 and R8 (they were the same) at constant 1.8V. One of the should have the dips in voltage at the same time as SB CE. NB! the input signal at R4 is 3.3V level.

    Didnt really understand why would R5 would come into play. Cant we do the switching via the sync button as before?

    Nice. Just a quick feedback:

    NewFile6.png
    As you can see logic is being transferred nicely from input to output. Levels are 1.8V to 0V when input changes.
    Is it possible to configure the output logic level to switch between 3.3V and 0V?
    EDIT: sync changes the outputs correctly

    Now back to cleaning up my messy wires so I can actually try to boot.

    there're no free 3.3v ports

    I can try to make RGH 1.2-based firmware (there will be 2 free 3.3v ports), but I'm too busy to finish the development :(

    Meanwhile I've successfully booted up retail from both nands. Switching works great. So 3.3V is probably not necessary. The waveform when retail boots up is much more complicated that reading or writing nand through j-runner. Thats why synchronization probably could of failed without CE linked up.

    Yet to try RGH.

    Everything works. Both RGH and retail boots fine. Switching works
    One question - does the new switching code require to connect SMC wire or not? Now it's not connected.

    the only difference between RGH and Retail SMC is unlimited booting attempts.
    so it can work w/o smc reset wire, but of course it's better to use it

    RichY,
    Hmm something fishy, when I connect SMC wire it does not respond to pushing power button, when I remove connection everything ok.

    RichY, есть такой вопрос. Если взять чип ACE с твоей прошивкой, подключить к нему +5 и землю, потом тыркать BUT на землю, будет он отрабатывать 1-2 моргания и переключать уровни на CE1 и 2? Дополнительных сигналов ведь не надо для этого?

    надо еще землю на C чтоб не светился всегда, а также подключить RST чтоб он знал, когда бокс выключен

    Подключить RST - это какую точку и куда, если без бокса, а просто на столе?

    таки доехали до меня сквирты, поставил сегодня дуал нанд, работает отлично, ставил на тринити, на радостях вместо 4 гигов памяти распаял флешку на 32 гига, лту в привод и вывел на морду индикатор. кстати паял без smc, с ним консоль не хотела заводить ретейл просто шумела кулером, а без него и кастом стал быстрее включаться

    с выходом последнего дашборда распаивать флешку стоит только для красоты (чтобы не торчала).
    а вообще молодец)
