RT1165's fuse config

Hi,

The fuses blew are blowed by mistake, and now Jlink can't connect device any more .

0x940[4] = BOOT_CFG1[4] = 1

0x960[4] = BT_FUSE_SEL = 1

My questions:

1. Is there anyway to make device boot from nor flash even if 0x940[4]  = 1?

2. Why Jlink can't connect device anymore if 0x940[4] is 1 (It should be 0 for nor flash) ?

 

Thanks,

Kyle

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Is there anyway to make device boot from nor flash even if 0x940[4] = 1?
-- No, I'm afraid not.
2. Why Jlink can't connect device anymore if 0x940[4] is 1 (It should be 0 for nor flash) ?
-- Actually, it shouldn't affect the Jlink connection, so I was wondering if you can illustrate the error message via sharing the screenshot.
Have a great day,
TIC
