RT1064 internal flash boot

[tarterkit_ru]

Hello, i have custom board based by RT1064.

Installed Keil and compile LED Blinky demo.

When i download to the flash (0x70000000 address) via J-link in debug mode, demo works well.

But not in the debug mode, demo not work - after reset RT1064 stay in serial downloader mode (sucess full opened by MCUXpresso).

Also i see firmware to the internal flash by J-flash (via J-link connection) utillite.

BOOT_MODE0 BOOT_MODE1 not connected (defult have pull down) - Boot From Fuses mode

I'm dont program any efuses and as understand, default value setting for internal flash booting.

What i lost, may be need burn BT_FUSE_SEL=1 ?

Hi,

BT_FUSE_SEL shipped value is 0, this means that if you are booting from fuses (boot_mode = "00") boot flow will jump to serial downloader mode. You need to burn BT_FUSE_SEL so regular boot flow is performed.

Have a great day,

Felipe
