Hi All
Hardware platform: i.MX7D
As below calculation is correct or not?
Thanks.
baud rate is 115200 / Tref_CLK is 24MHz (0.0416us)
UA1 Spec min= 1/115200 - 0.0416 = 8.6384 us
UA1 Spec max= 1/115200 + 0.0416 = 8.7216 us
UA2 Spec min = 1/115200 - 1/(16*115200) = 8.68 - 0.00000054 = 8.67999
UA2 Spec max = 1/115200 + 1/(16*115200) = 8.68+ 0.00000054 = 8.68000054
Solved! Go to Solution.
Hi Felix,
UA1 Spec min= 1/115200 - 0.0416 = 8.6384 us
UA1 Spec max= 1/115200 + 0.0416 = 8.7216 us
I don´t know how you calculated these values, but they should be ipg_perclk/RFDIV

Hi Carlos
Do you have any comments for this case?
Thanks.
Hi Felix,
I am sorry for the delay, that looks corrects now.

Hi Carlos
reference as below result,
T_ref_clk is 24MHz/6=4MHz.
1/T_ref_clk=1/4MHz=0.00000025
1/buad rate=0.0000086806
UA1 Spec min= 0.0000086806 - 0.00000025 = 0.0000084306 s
UA1 Spec max= 0.0000086806 + 0.00000025 = 0.0000089306 s
Is the above is correct?
Thanks.
