Booting picozed

Hi,

I don't have sd card at hands,I want to know booting picozed with QSPI must need sd card? I refered to http://zedboard.org/support/design/4701/76

Application Note on Booting PicoZed Using QSPI and eMMC

But all they need sd card.

Thanks,

Hello Wangy,
I refered you to a post previously were I referenced a lab that uses JTAG to program the flash memory to boot from QSPI. No SD Card required.

Did you ever get it working? Did any of the suggestions we offered help?

Piggybacking on this question...

I have a 7020 Picozed and the FMC Carrier Card V2. The "getting started" pamphlet that came in the box says "Do not boot a stock PicoZed in QSPI mode on the FMC Carrier Card V2. This could damage your carrier or SOM."

So even if I have no SD card, I am not able to program my boot image into my PicoZeds flash and boot from that? Going from the labs you linked to above, it sounds like I can, so I am a bit confused.

The key word is "stock" -- do not boot a __stock__ PicoZed in QSPI mode. The PIcoZed ships with the QSPI pre-programmed with a factory test that assumes it is plugged into an FMC-V1 card, which is what is used at our factory. Therefore, you should not take a PicoZed out of the box and boot the pre-programmed QSPI when the PicoZed is plugged into your FMC-V2 card as the peripherals on the V1 and V2 do not match exactly.

You can certainly reprogram the QSPI on your PicoZed to work with the FMC-V2.

Also, the FMC-V2 ships with an SD Card, so you should also have that as an alternative boot method.

Hi JFoster,
Yes,I can also use JTAG to program the flash memory to boot from QSPI, but it have not introduct how to boot Linux with QSPI. For examble FSBl、
.bit、u-boot(boot.bin)、uImage,how these files can program into QSPI and boot linux without SD card？

Hello Wangy,
Is there any reason why you do not want to use an SD card?

Hi JFoster
I booted linux with QSPI(without SD card) in zedboard in the past. So I want to test picozed whether it can boot linux with QSPI .I use the same way ,but failed. My way is to combine fsbl.elf、bitstream、u-boot.elf、uImage、devicetree.dtb、 uramdisk.image into boot.mcs(create boot image with SDK),then program boot.mcs into QSPI flash, but failed(printed "can't get kernel....").

Hi Wangy,
Unfortunatly I do not have any experience in programming the QSPI and eMMC without using an SD Card. I am going to suggest you try asking your question at the digilent forum since they are the main point of contact for educational purposes.
