BT_FUSE_SEL confusion on i.MXRT

Hello,

 

there is some confusion about the BT_FUSE_SEL fuse in the RT1064 Reference Manual (Rev 2. 07/2021). On page 198 you find:

while on page 1331 you find in table 22-6:

In both tables the resulting options for boot_mode 00b and 10b are swapped. Which one is correct?

 

Thank you for your help.

Hi @glaukos ,

  Thank you for your updated information, the first one is correct:

You just need to know, if the BT_FUSE_SEL is not burn, then BOOT_MODE[1:0]: 00, 01, is the serial download mode, 10 is the internal boot mode from GPIO.

 

Wish it helps you!

If you still have question about it, please kindly let me know.

Best Regards,

kerry
