SD card can read or write exsist file, but any create (file/dir) crash the system. #10329

Closed developer-ken closed 1 month ago

developer-ken commented 1 month ago

Board

ESP32-PICO-V3-02

Device Description

Custom made PCB with a ESP32-PICO-V3-02 and a TF card slot. Since both reading and writing exsisting files works fine, I don't think it is a hardware problem.

IDE Name

PlatformIO

Operating System

Windows11

Description

Open an exists file on sd card for writing, reading or appending works just fine. But when I want to create some file/dir, just crashed.

For example, when "/test1.txt" does not exists, it crashes. When it exists, code works fine and content is actually written to the file.

Please provide a minimal example that can be compiled and demonstrate the error. Your backtrace looks a lot like an out of memory error while the SD card is initializing, and doesn't seem to have anything to do with file access.

developer-ken commented 1 month ago

Thanks a lot for your effort helping. I've changed the code a little bit and get a more related stack trace. So when /test1.txt exists, it works just fine. I verified that text is written into that file. But when I delete /test1.txt in the card and run that again, I got a crash. https://github.com/developer-ken/SCIRecorderFirmware/blob/e5017fb963ef7481c5ad1c354b4d5019cdc0e817/src/main.cpp#L116

If those information is not useful, I may write a minimal schetch to reproduce the problem at weekend.

lbernstone commented 1 month ago

Still looks like a memory error. Can you disable psram and see if you get the same issue? Check your memory availability with ESP.getMaxAllocHeap() before the file write.

developer-ken commented 1 month ago

Thanks for your info. Disabling psram works. With psram enabled , I add a line to print ESP.getMaxAllocHeap() :

I disabled psram by

build_unflags =

and it works just fine.

What can be the problem here?

lbernstone commented 1 month ago

Something with how the psram is implemented in pico. @P-R-O-C-H-Y @SuGlider Do you have a pico-v3-02 device available to test this?

me-no-dev commented 1 month ago

@developer-ken which pins are you using?

lbernstone commented 1 month ago

pins 6-11 are not available for use by the SD card, they are used by the flash card. Use different pins

P-R-O-C-H-Y commented 1 month ago

I have got only pico-v3-zero here without PSRAM unfortunately.

developer-ken commented 1 month ago

I double checked and find out I used the pin connected internally to psram for SD card SPI. I've already made a PCB with the wrong pin config so I have to use the chip without psram now. Maybe change the BOM to use pico-v3-zero, as I have to disable psram anyway.

Its my fault not checking pin configuration carefully before odering a PCB. It's confusing me that ESP32-PICO chips have those internally connected pins wired out.

Anyway, thanks for you guys helping solving this problem. I will close this issue.
