Hi,
We noted in the errata (Issue 133) that the radio performance is significantly degraded if the QSPI is enabled. The suggested workarounds are to 1) lower Vdd to 1.7 to 2.0v or 2) only access QSPI when the radio is not operational.
In our application, we access the QSPI is memory-mapped mode every 500msec for tens of msec at a time resulting in a low duty cycle access time. Are there uses cases which would allow both the radio and QSPI to function at the same time? Would lowering the QSPI clock rate help? Does the impact occur by simply enabling the QSPI peripheral without clocking? If you have any information elaborating more on the cause of degradation that would be helpful.
Best,
Kurt
