This is a heads-up:
System configuration: T3-BB and three T3-80s.
The code on my system was executing great when I was using firmware (mini_arm_rev46.6_2.7.hex.)
Last week I upgraded the firmware to: (mini_arm_rev46.9_4.19.hex).
When I did this some of my code stopped executing. So last week I kept updating with (rev47.0_4.26.hex) and today I tried (rev47.0_4.28.hex).
I tried several simple program commands but still couldn’t get all of the code to execute. I just reinstalled (rev46.6_2.7.hex) and the code is executing again.
I’m posting this as feedback and to maybe offer a temporary workaround if anyone else is experiencing this.
