RP2040 generic

[madmai]

I use this how rp2040 https://imgur.com/8IVB1Z4 and no Works, sometimes blue led blinking not ever and this works randomly sometimes green led fixed sometimes blinking this is original rpi picohttps://imgur.com/HICGgex

what can i do for 2 versions works, pi pico original sometimes works, but the black one, never works, anyhelp is apreciated, thx

i use two with picomencard+ with micro sd, green sometimes works but black board never works, thx

fixed green led https://imgur.com/05iXILt, but i do nothing, fixed alone, .... strange...

I discover the pipico original works fixed, but generic black one works too, but i thing has no permission or bad connection with sd, in black one open with selec+start+triangle and enter on memory card stage, but not write file in sd....

I don`t know what happen, but not read or write in sd card..... pico memcard+ works in pico and black one, but not read/write sd

any help? something are wrong picodrive original not show singles saves in mc, but the led is fixed... help?

To solve this I will need more information:

• Which version of picomemcard are you trying to use?
• Which devices are you using with it? You mentioned one original pico and one black, I need more informations about the second one.
• Have you checked the soldering joints with a continuity tester to make sure they are good?

https://imgur.com/NCuncBR now i'm using this, and yesterday works, but now blinking led green in original pi pico, with release pico 1.0.2, before i test too 1.0.3 pico, but now version i use is 1.0.2 pico, i have those too https://imgur.com/ovCDs9p i build 2 memcards adapter to plug in psx, and when i have i test 3 models, with 1.0.2, black one, purple on and pico original, i tell something when i have, i thing in the one i have build the conectivity is not the problem sometimes works, sometimes blinking in pico original, now is blinking, if you want tellme in pm too, thx, for your attention

i have been notice when i quit original one, i test without nothing in memory card, switch off anything and controller works better when i quit pico original and test without nothing, when i put pico original controller not works properly to press x i had to do 3 o more times, for you aknolegde, excuse me for my bad english, i'm spanish, sorry for the language, thx

in first image of this comment check if vcc cables are been connected, i put those 2 vcc cables in image in red in pico original y 5th pin white cable, 3.3v, Is Correct? or i must have to connect in another way, thx

I'm sorry but I'm having trouble understanding everything. From what I can tell if you are experiencing intermittent issues (working for a bit than not working) I think the most likely cause is some sort of bad connection

I think i need 2 red cables vcc, it's correct? someone can explain me, how to feed vcc 3.3v micro sdcard , and how to feed pi pico vcc voltage, please explain me scheme of feed voltage map in pico drive and micro sd, i think this is the problem, only voltage feed schema, for disolve my dudes... thanks for advance to all people, thx again

I believe the adapter from this picture needs 5v on VCC (and does its own conversion down to 3.3V) so you need to connect the Pico VSYS (pin 39) to it. Question: the Pico is powered by the PSX right?

[madmai]

i think the psx 3.3 v memcard port not works properly only do 1.5v(maybe with tests brokes), i think i repaired to 3.3v memcard port now, but tell me how i have to connect pi pico voltage and sd voltage i have others sd ports works in 3.3v, if you can tell me how i have to connect pi pico and sd card, the scheme vcc connections in pi pico, thanks in advance, in the project image, this image, tell me how to connect pi pico to receive 3.3v and how connect out to sdcard port, i don't understand in previous image please, can you specify me, where connect from mc 3.3v to pi pico and sd port voltages vcc port?, first of all, thanks a lot for your attention and replies, thanks again, and my apolyge for my english, i'm spanish. i wait a reply, thx

I have trouble understanding everything but here is what you need to connect:

1. To power the pico: MemoryCard 3.3v <--> Pico VBUS (40)
2. One of these:
   • To power the SD module (if it has it's own regulator): Pico VSYS (39) <--> SD VCC
   • To power the SD module (if it needs 3.3v): Pico 3V3(OUT) (36) <--> SD VCC
3. Ground must be in common for everything (GND on PSX, GND on Pico, GND on SD)
