Hi, I have a running Petalinux system (TE0820) on a SD card.
The SD card has two partitions:
- FAT32 (boot), which contains the BOOT.BIN and the image.ub;
- EXT4 (rootfs), which contains all the extracted rootfs.tar.gz file.
I've generated the BOOT.BIN file using the following command:
petalinux-package --boot --format BIN --force --fsbl images/linux/zynqmp_fsbl.elf --fpga ./bitstreams/my_fpga.bit --u-boot --kernelNow I've two questions:
Firstly, I've to move the system from the SD card to the internal flash, how can I do that?
Secondly, I've to add the possibility to update a running system in terms of bitstream and internal Linux services.
Because for updating the Linux services could be easy (I think that a SSH connection in order to update the binaries could be enough), I would like to know how I can update the "embedded" bitstream file which is inside my BOOT.BIN file in the boot partition.
Do you suggest to rewrite completely the internal flash? How can I perform such update? It is possible to rewrite the entire flash with a new system image through the ethernet port? Which documentation do I have to follow for such goals?
PS: The system is running on a custom carrier board with both Ethernet and SD card access.
Thank you.
