Hi,
Can Vybrid boot from a QSPI Flash connected only the QSPI_B?
When the QSPI boot, First, the Vybrid set the pin mux and tries to get the QSPI configuration parameter from all Flash.
QSPI_A is always enabled but the optional configuration is that QSPI_B is enabled. So I think the Vybrid cannot boot from the only QSPI_B flash. Is it correct?
Solved! Go to Solution.
Hi Hiroki,
That's correct, you must always boot from QSPI_A. You can use QuadSPI0 or QuadSPI1, as that is selected by fuses, but on QuadSPI0 you have to have all the information in QuadSPI0_A.
See this thread for more information on QuadSPI booting. Parallel QuadSPI
