Hi team,
Here is an issue may need your help:
Designing a board for a DAC application for radar wave based on TDA3MV, the following issues were found in debug:
For QSPI configuration, configured in QSPI_1 mode (SYSBOOT15-0:1000000100011000), it can be measured that QPSI_CLK has a clock output of 12M and QSPI_CS has a waveform output. The SBL file is burned and running properly.
However, when switching to QSP_4 (SYSBOOT15-0:1000000100011001) mode, both QPSI_CLK and QSPI_CS have no waveforms, but QPSI_CLK should have a 48M clock output. The burn is normal, but the QPSI_4 mode burn will cause an error to be reported at verify. And cannot work. QSPI_CLK always has no waveform, when switching to QSPI_1, a file burned in QSPI_4 mode can run, indicating that the burn was successful at that time. just the QSP_4 is not responding.
The customer would like to know what's the reason for that. Could you help check this case? Thanks.
Best Regards,
Cherry
