1. How did you update bootloader from 1.65 to 1.70? Is it possible to revise it back to confirm if the problem was caused by different bootloader version?

2.  I didn't see any existing report for bootloader 1.70. So to position the issue, please do some test:

- test it with a simple demo code, for example, toggle a led. Is it work normal on both 1.65 and 1.70?

- test system clock. Are both of them the same system clock?

- which module can't work normal on 1.70?

Have a nice day
