RichY, Hmm something fishy, when I connect SMC wire it does not respond to pushing power button, when I remove connection everything ok.
Everything works. Both RGH and retail boots fine. Switching works One question - does the new switching code require to connect SMC wire or not?...
Meanwhile I've successfully booted up retail from both nands. Switching works great. So 3.3V is probably not necessary. The waveform when retail...
Nice. Just a quick feedback: [ATTACH] As you can see logic is being transferred nicely from input to output. Levels are 1.8V to 0V when input...
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...
Ok here is what I think is going on Here is a picture of what is happening when data is being exchanged with NANDs (from Hynix datasheet). CE# is...
Connected post to FT6U7 reconnected nand track back on motheboard Following observations: 1. when nothing connected on ACE ce1 ce2, track is...
Did a little investigation by just gradually eliminating stuff that I changed after successful glitching when I added the second nand. After...
Thanks for the help, you have been very helpful. OK I'll dig in further on my on, time to dust off oscilloscope. It would just make my...
I double-checked wrote to them and re-read they are fine. Writing to one does not overwrite the other. Question - does the ACE keep CE1/CE2 at...
To me the most suspect in the voltage on CE1/CE2. Its only like 1,8V depending which is selected. I looked up the memory specsheet and it says its...
Resoldered NAND on bottom side. Connected button, ce1, ce2, smc on top side, removed nand track patch. Checked that both nands can be read...
E4 works really well: 7s, 7s,7s,7s, 7s,15s E5 works worse: 20s, 36s, no boot(over 3min),15s, 36s
E4 and E5 both boot E6, E7 dont, not even once. E5 is a bit more consistent than E4 which in one occasion hung. E5: 44 sec, 8 sec, 22 sec, 50...
are they still for FT6U1?
I feel unqualified to answer, I'm uploading a video so you can see (will take time). From what I see 90% video consists of Short-Short-Long...
so JA_L_0.5_T_59.7.xsvf also "worked" with retail nand? yes This time waited longer E8 didnt start for 5min E7 worked, but the boot took couple...
Its just that in my previous attempt with dual-nand even the retail image would not boot.... OK, but back to testing Here is what I did: -...
Never mind. Already desoldered NAND again resoldered post to FT6U1, restored track, and tried files. I'm a bit puzzled ad they all seem to boot I...
Damn I'm already half-done soldering back NAND, is it crucial to test these?
