K81 with QSPI/XIP and high IRQ rate

i have a K81 with QSPI and some ADC code that should run from the QSPI. 

My first test gives some strange results, from internal flash averything runs ok, but when i move the IRQ handler to QSPI a simple LPUART communication lost some characters, sometimes.


My question is, can i run any code, even a high rate IRQ handler, from QSPI (XIP) without influence other stuff?
