Multiple boot methods using the same jumper setting

Question

Hi,

I am working with Petalinux and micro zed board. I am able to boot the the Zedboard using both QSPI flash and SD card. However I would like to know if by having the same jumper settings, can I boot from a different method. For example, if I set the jumpers to SD card mode, can I still be able to boot through QSPI without changing the jumpers?

PS following for jumper settings (page 20): http://microzed.org/sites/default/files/documentations/MicroZed_HW_UG_v1_4.pdf

Hello Yathindra,

No, per chapter 6 of the Zynq Technical Reference Manual (UG585) the boot jumpers are only sampled at POR (Power On Reset) by the Zynq's internal BootRom and that sets the boot source until another POR occurs. You can download UG585 here:
