hey i cant figure out how to get my orange pi PC 2 to boot

rajkosto: what exactly is your problem, what have you tried so far?
<rajkosto>
i dont even get any serial output on the header, or any usb device when i plug into microusb to see if its in FAL mode
<rajkosto>
should the power LED be on regardless of OS ?
<rajkosto>
no LEDs are on
<apritzel>
rajkosto: do you have a micro SD card inserted? AFAIK the SPI flash is empty initially, so you need a boot image on the SD card to see something
<rajkosto>
shouldnt that automatically put it into FAL
<rajkosto>
i had a orangepi zero that didnt have soldered NOR flash and i was able to program it via FAL that way once i soldered on some
<rajkosto>
i dont know if whatever i put on the microsd is working
<rajkosto>
if it can read the microsd at all
<apritzel>
yes, if the SPI flash is really empty, it should go into FEL mode
<apritzel>
but if there is something with a valid header on it, it might get loaded, but then crash
<apritzel>
in any case an SD card is always first boot priority, so you can fix that
<rajkosto>
shouldnt it say HELLO! on the uart or something anyway
<apritzel>
have you checked that you got RX and TX wired correctly?
<rajkosto>
yeah i swapped them
<rajkosto>
should be 115200 right (doesnt say this anywhere on the wiki)
<rajkosto>
whats so special about PhoenixCard utility btw
<apritzel>
rajkosto: forget about PhoenixCard or the other Allwinner provided crap
<apritzel>
because nobody can answer you that question, really ;-)
<apritzel>
the content of the file needs to go to sector 16, so use just "seek=16", or "bs=8k seek=1", like above, or "bs=1k seek=8" (all the same)
<apritzel>
also: the LEDs are both GPIO driven, so nothing will light up until some software tells it so
<apritzel>
you can check the voltage on the GPIO header pins to see if it gets power
<rajkosto>
yeah i can measure 3.3v, 1.4v and 1.1v on the inductors
<rajkosto>
still not doing much
<rajkosto>
oh the h5 is pretty hot now
<rajkosto>
nvm its pretty hot regardless
<apritzel>
so it works for me: on power on it loads some U-Boot from SPI flash, but if I put an SD card with fel-sdboot.sunxi in, it goes into FEL mode
<rajkosto>
i still get nothing on uart or usb
<apritzel>
FEL mode is somewhat picky about proper reset, though, and there might be some stale voltage via the UART cable, or even the OTG port
<apritzel>
so it helps to remove all cables, then put them back on, to force a proper power-on
<apritzel>
and your FEL setup is correct? If you have the OPi-Zero ready, you might want to double check it there.
<rajkosto>
i accidentally killed that by powering it up backwards
<rajkosto>
got something that would blink the leds if put on microsd ?
<apritzel>
backwards? and are you sure it's dead? In my experience those boards are surprisingly robust, but it's easy to mess the wiring up, and get no output, so one *thinks* it's dead
<rajkosto>
nah it gets blazing hot on the dc2dc
<rajkosto>
shorted
<rajkosto>
it got -5v ;)
<apritzel>
ouch
<rajkosto>
pretty sure i didnt kill the PC 2 tho
<rajkosto>
it just stopped working because the microsd in it got to write limit
<rajkosto>
but now i forgot how to set it up
<apritzel>
yeah, I guess those boards without a PMIC don't like being mistreated like this ;-)
<apritzel>
I don't have anything blinky ready, would be board specific anyway, but I can bake something tomorrow
<apritzel>
(it's getting late here)
<rajkosto>
i should get a device notification when i plug the microusb into my computer right
<rajkosto>
i know that worked immediately on the zero cuz it could get power from microusb too, but not this one needs a DC barrel jack
<apritzel>
rajkosto: yeah, I think the micro-B is correctly wired on that board, so you need the barrel jack
<rajkosto>
i know i do, i have a charger doctor on its usb outputs to see when its powered
<rajkosto>
anything i can put on microsd to get u-boot on there ?
<rajkosto>
anything on uart really
<apritzel>
you can just build U-Boot for it: make orangepi_pc2_defconfig; make
<apritzel>
even with missing TF-A you should see SPL output
<rajkosto>
i dont have a way to make anything sorry
<apritzel>
armbian should have some image, just the first Megabyte should suffice to see something on the UART
<rajkosto>
i have armbian on a microsd it still does nothing
<apritzel>
the same dd cmd like above
<rajkosto>
doesnt pine64 have a different uart they use

how warm is it supposed to be when you put your finger on the h5
apritzel has quit [Ping timeout: 480 seconds]
<rajkosto>
guess what it was the NOR flash
<rajkosto>
desoldered it and now i get FAL on usb when i plug it in ;)

i guess i will flash ./usr/lib/linux-u-boot-current-orangepipc2_21.08.1_arm64/u-boot-sunxi-with-spl.bin from the armbian to NOR as its empty atm
<rajkosto>
i put the NOR back on with that flashed and now its in the same state as before (no output, no FEL)

verified data read by sunxi-fel spiflash-read is the same as what i flashed with external tool
<gamiee>
rajkosto as far as I remember, you need special image for SPI boot (but I might be wrong)
<rajkosto>
i actually just wanted to get something on uart
<rajkosto>
dd of fel-sdboot.sunxi to sdcard does make it go to fel but doing the same with uart0-helloworld-sdboot.sunxi i get nothin
<gamiee>
what board you have?
<gamiee>
not every board uses uart0 as "default TTL"
<rajkosto>
orangepipc2
<rajkosto>
the /usr/lib/ folder i found was in the armbian for it once its on my microsd
<rajkosto>
ok so whatever i put on the NOR is working, cuz when i had uart0 on NOR FEL didnt work, but when i put fel-sdboot.sunxi on the NOR it does go to FEL
<gamiee>
thus uart0 isn't used as uart on your board
<rajkosto>
oh i put the armbian microsd and the green led came on
<rajkosto>
yeah the uart just doesnt work

apritzel, for no reason after i desoldered, flashed, and resoldered the SPI chip everything started working as expected except still nothing on UART
<rajkosto>
(it was all 0xFF after the desoldering anyway so no idea how it could have affected anything)

rajkosto: is your SD card good? I saw problems yesterday, where sometimes it would boot from it, sometimes not. Might be power related?
