Compatipel with that pico? #51

Open Liriel-666 opened 11 months ago

Liriel-666 commented 11 months ago

20231225_002048 Is the lite version of the board compatible with that pico 2040?

kbeckmann commented 11 months ago

No, not without modifications. Notice the pins vin and vout, and compare with the original or weact pico board.

Liriel-666 commented 11 months ago

is Vin and Vout the only difference? sry i am not that big in the pico thing and for me the rest looks good

Liriel-666 commented 11 months ago

to what i can see the pinout ist most the same to the non weact pico. i see some difference in the last 10 pins but i dont now how to fix it. What pin of the lite 1.4 board must connect to what pin on the black pico board?

Were you able to use this card? I bought the same one and did all the soldering points but it doesn't generate an image on the N64 =[

curcius commented 10 months ago

Updating, I was able to run Homebre as Testrom and a cell phone game converted to UF2, but the Nintendo 64 games don't start at all. I've checked pin by pin and there are no shorts or soldering failures.

It might be related to region-checking and not having the correct one selected when making the UF2 file? or CIC issue?

Did you reconnect VREF to GP29? the VREF jumper isnt connected on the board i got, but is in all the pics of that board.

Thank you for responding, but I've tried everything and neither UF2 NTSC nor PAL M works, I've tested several games and nothing, I've closed and opened the jumper and it gives the same results... I believe it's some incompatibility with the flash, no. I can think of nothing else, the rpi works, I've tested it with other programs like Micropython, but 64 games don't run, just homebrew...

I managed to solve it, I had to use the 3v3 from the console board directly on the RPI, I was using the RPI's USB power supply and it didn't work, I made the jumper to the 3v3 on the RPI and it worked perfect. Thank you everyone, I hope the project moves forward. 20240119_123903

i dont get my to work with a weact pico 20240119_174603

I solder all correct. because i destroy on unsolderng the other pico i replace the jumper with a cable all solderpoints are there and correct. i even solder the debug port

nothing with any uf2 convertet file. I put firmware on it and then restart it. then i put the testrom or a game on it and nothing on my pal n64

@Liriel-666 i have the exact same problem as you. I ordered like you a WeAct RP 2040 and nothing is working. Did you solved it in the meantime? GPIO 26 and 27 are shiftet one pin could that be? There is no "RUN" pin on the WeAct compared to the original Pico board? comparison-with-PicoCart64-schematic.pdf

Update: debug port has no connection on pcb. GPIO 26/27 doesn't matter if i am right. I don't know why the WeAct 2040 16MB is not working?!

samowitsch commented 3 months ago

@kbeckmann Neither the WeAct 16MB nor the Bitfunx 16MB Pico board works. Are there any secret tips that aren't mentioned anywhere? Does the picocart64-v1-pal/ntsc.uf2 work with any Flash Ram size?

I'm sorry, I don't know to be honest. WeAct 16MB have been known to work earlier, but it's also possible that the manufacturer changed something, e.g. maybe the flash is not the 133MHz variant or so?

Edit: This was meant as a reply to @samowitsch

The following "solutions" work for me. (By the way, thanks for the feedback on Discord from be0w0lf710, which pointed me in the right direction. I would never have questioned BSS84 that something is not working properly here.)

I just want to put a warning text here and say that you need to be careful and know what you’re doing if you are connecting it like this. You risk connecting your 5V USB supply voltage to the N64 3.3V rail which could cause damage.

reflekt00 commented 1 month ago

@samowitsch has this setup bridging 5V on the weact board to the 3.3V rail been working reliably for you? I'm in the same boat, the cart won't load a rom with the transistor in place.

samowitsch commented 1 month ago

@reflekt00 it worked for me without the components and just a jumper wire. But with this „workaround“ the USB cable should not be connected when the picocart is plugged into the N64.
