Hello, At the moment I'm only testing the UART communication with the
AC4490( a transceptor ) and it seems to work, I made a mirror with the UART.
The transceptor send a char for UART, and UART sends it back to the
transceptor. But, always when I send the following sequency by transceptor,
one to nine three times, (123456789123456789123456789) it always went back
from UART (123456781234567123456) i.e. missing 9, 8, 7. The same pattern
happens with any sequency with many characters. I think it would be a
problem with oscilator, because I'm not using external oscilators. The
frequency of operation in my test was 4.13MHz and UART velocity was 9600baud
(for both, AC4490 and UART). I thought that the problem verified in UART
would be due to J-TAG, but I can't verify it because when I remove J-TAG,
the transmission don't occur. Please, someone have any idea? Thanks Daniel
