How do I enter BOOT mode on M5Core2: Wrong boot mode detected (0x0)! The chip needs to be in download mode

theMusicMan — Invalid Date

@ajb2k3 said in How do I enter BOOT mode on M5Core2: Wrong boot mode detected (0x0)! The chip needs to be in download mode:

@themusicman This means that something else in OSX is access the USBport via a terminal preventing M5Burner from being able to access the port.

Please make sure only M5Burner is running and that no other terminal software is running.

I tried on my MacBookPro (original issue was on iMac) with no other serial terminal software running, exactly the same issues unfortunately. I have now returned the M5Core2 device back to thePiHut and am awaiting a replacement.

Thanks for your support though @ajb2k3 - it is much appreciated.

Load and write blocks of 512 direct to sd card M5Core2

Powersoft — Invalid Date

Is it possible to read/write blocks of 512 bytes direct to the sd card?
This without using the M5Stack filesystem.
I know with the SDFat.h library it is possible, there are commands for readBlock(block,buffer) and writeBlock(block, buffer), and buffer is defined as
byte buffer[512].
But I get not compiled this library under my Core2.
Appreciatie any help with this.

Cheers,
Jan

Solution to make Button disappear

Re: [Core2] make Button disappear
Re: [Core2] make Button disappear

I found the following solution, which works for me (extract only):

Button* button1 = NULL;
// create button
if (button1) delete(button1);
button1 = new Button(0, 0, 158, 80, false);
// disable button
button1->delHandlers(_softButtonEvent);
// the following line is optional, does not change anything if button is deleted
// button1->erase(BLACK); // documentation in M5Button.h -> line 716
delete(button1);

// that trick does it; other approaches did not work reliably
button1 = new Button(0, 0, 0, 0, false, "");

[UIFlow] Add micropython libs for M5Stack Core, Core2

GLP — Invalid Date

Hello, could be great to simply include/upload libs already shared for micropython (eg putting in a /lib path). It may expand a lot of capabilities (eg for HW ds18b20 or for SW Email sender etc). Better if Blockly section of UIFlow could accept some changes applied to Python section (at least the values)
