SDM & Configuration Interface
- Are there any SDM commands that allow uploading a bitstream, similar to the JTAG instruction 0x002 used for configuration?
- Could you clarify the AVSTx8 (Avalon Streaming x8) programming interface protocol:
- What is the data format and handshake mechanism?
- Is it strictly limited to configuration use, or does it allow other use cases?
- Is it possible to use the SDM pins (AVSTx8 interface) as a high-speed data path from an external host to the HPS?
- For example, could it be used to transfer a U-Boot image to SPL after HPS boot?
Hi
For AVST Programming interface protocol you could find more details under the link below:
https://docs.altera.com/r/docs/683673/25.1/agilextm-7-configuration-user-guide/avalon-st-configurationAn external host could be used to program the FPGA and HPS configuration only.
The Uboot image and rootfs would need to be placed in a storage that could be access once the HPS is brought up.Regards
