Zynq 7000 bitstream encryption property not supported

Jump to solution

Section 6.3.6 of the Zynq-7000 TRM (UG585 v1.8.1) says that we can use XIP for SMC NOR, however:

 

1. when I use bootgen to make BOOT.bin I get an error "Execution Address of FSBL is out of Linear QSPI range in XIP mode" which is correct because my FSBL is in the SMC range. Why doesn't bootgen make a BOOT.bin file for me without error?

This is my boot.bif file:

boot_image:
   {
   [init] etc/boot-reg-init.int
   [bootloader,xip_mode] build/fsbl.elf // 1st partition, first stage boot loader
   build/ssbl.elf // 2nd partition, second stage boot loader
   }

 

2. So I removed ",xip_mode" from the boot.bif file, make BOOT.bin, then set both the Image Length and Total Image Length to zero in BOOT.bin (and fix the checksum). Boot fails and I get undocumented BootROM Error Code 0x2104. What does that error code mean?

Yes, that applies to QSPI interface to NOR, but not the SMC interface to (parallel) NOR that I am using. Thanks.

Pratham, thank you very much. And sorry about the subject line; I'll make a more relevant one next time I have an issue.
