Hello, I am trying to program the flash chip of a Zybo Z7 board (Xilinx Zynq 7020) using OpenOCD. As the flash chip is not directly accessible through the JTAG line, I had to use indirect programming. U-Boot was a good option for that. I prepared UBoot for the board. From Xilinx SDK, I can load the U-Boot's elf file and then use its terminal to load the .bin file and program the flash. But I cannot do that from OpenOCD. I can load any other programs (.elf files) on the chip and run it using OpenOCD. But I cannot load the U-Boot program. Bitstream loading works (LED light-up), I can also run the fsbl (at least it seems that way) but after loading the U-Boot elf file, when I resume, it does not work. Again, I works for all other elfs I tried, just not the UBoot elf. (All use the same fsbl.elf) Any suggestions? I am attaching the script I am using.
