It seems no one is using Arduino software for M5Core2 :(

Everything is reproducible here: https://github.com/PierreRambaud/pokegotchi/tree/try/partitions

Hi everyone,
I bought a M5Core2 with Flash 16MB and PSRAM 8MB, but with PlatformIO, I'm not able to use the whole space.
I created a partition csv file (see below), but it seems not really working well

# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,     0x9000,  0x5000,
otadata,  data, ota,     0xe000,  0x2000,
app,      app,  ota_0,   0x10000, 0xff0000,

I always receive this kind of errors:

.platformio/packages/toolchain-xtensa-esp32/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: .pio/build/m5stack-core2/firmware.elf section `.flash.rodata' will not fit in region `drom0_0_seg'
.platformio/packages/toolchain-xtensa-esp32/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: region `drom0_0_seg' overflowed by 247536 bytes

I really don't know what to do with that.
Without my little change, platformio returns:

RAM:   [          ]   1.8% (used 119212 bytes from 6553600 bytes)
Flash: [==        ]  20.9% (used 3485493 bytes from 16711680 bytes)

So I should have available spaces ^^'

Any idea?

Ok, I bypass the problem by using SD.begin() and SD.end() each time I need to use SD methods

I'm facing a weird issue.
When I use the SD.exists or SD.open on different CPP files, everything works well, but when I click on the reset button, an error occurred.It's also happening when I try to save a file on the SD card twice.

I have to remove and reinsert the SD card every time which is a little annoying.

What I'm trying to do is check if there is an SD card available, if yes, I can add a button to save the current game state, or I'm able to load the JSON stored on the SD card.

[  1788][E][sd_diskio.cpp:199] sdCommand(): Card Failed! cmd: 0x00
[  1788][E][sd_diskio.cpp:795] sdcard_mount(): f_mount failed: (3) The physical drive cannot work
[  2095][E][sd_diskio.cpp:199] sdCommand(): Card Failed! cmd: 0x00

Everything I do is public: https://github.com/PierreRambaud/pokegotchi/

I'm not sure it's the right approach as I started C/C++ one month ago.

It seems no one is using Arduino software for M5Core2 :(

Hi,
I'm a new user using an M5Core2 with the Arduino software as it's recommended in the documentation.
I'm facing an issue and I don't find any way to debug backtrace stack.
I tried with Esp Exception Decoder but I always receive this kind of exception:

Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.
Core 1 register dump:

Is there a way to make these exceptions more human friendly? I don't know what to do with it, and it's funny because the ELF file is always 0000000000000000.

@erich you did more than you think.
Feel free to ask when you will need it, if the M5Core2 is enough to run your program, I would be glad to help as you did

OMG, it works as expected! <3
If both of you have GitHub account, I'd be glad to add you as credit for the awesome help!

Thank you @macsbug , this is exactly what I add to edit in my lv_conf.h in order to make it works!

@erich I updated my repository, it now works, but not as expected. I've two issues:

• I'm not able to change the label text each time I press a button (the reason of the seg fault)
• I'm not able to draw on the right side like the lvgl take the wrong space, or the tft I don't know yet which one ^^'

After that, everything will be ok (at least for this first project)

As you said, a good platform for development is the key, I work with emacs for years, but I never configured it for C language.
I've Arduino software open beside, only to compile & transfer.

FYI, I correctly display a button, I have many things left to do next, like finding the reason why my DrawingBoard.cpp pointers are badly set, but in the end, you help me a lot!
Thanks again!

For people reading this, I'll do my best to improve my GitHub repository in order to have a simple example for M5Core, explaining which parameters must be configured in lv_conf.h :)
