The TDA3MV work normally after power-up(NOTE: board is built on by customer himself with the TDA3MV chip ) , as shown in the following figure:
But the SCLK clock for measuring flash with an oscilloscope has no signal (NOTE: flash chip number: MX25R1635FM2IL0), and the schematic is shown below:
ISSUE:
Does the QSPI interface need to be configured to run a flash program while the TDA3MV is powered up or can a normal SCLK clock signal be measured with an oscilloscope as long as the TDA3MV is running properly?
Could you help to resolve this case?
Thanks!
Best Regards,
