Performance problems:
|
||||
|
||||
It seems the problem is that the actual flash programming takes time.
|
||||
hal_delay_us() is invoked between each time the
|
||||
CPU is polled for whether flash programming has completed.
|
||||
|
||||
|
||||
Flat profile:
|
||||
|
||||
Each sample counts as 0.01 seconds.

||||
