Changes
#1 Change DDR3 RAM (U15, U19) from IM4G16D3FABG-125I to IS43TR16256BL-125KBLI
Type: BOM change
Reason: Component is end of life.
Impact: New DDR timings may be considered in designs. DDR3 setup used in reference design is known to work still.
#2 Replaced Flash (U4) to IS25LP512M-RHLE All SoMs use S25FL256SAGBHI20 Flash (U4)
Type: BOM changeReason: Ensure long time availability.Impact: Jedec Manufacturer ID changed from 01h to 9Dh, the device ID from 18h to 19h. 512Mbit flash are now available.
Type: BOM change
Reason: The planned IS25LP512M-RHLE is listed as 'Supported Flash Memory Devices for Artix-7 Device Configuration' in Xilinx UG908 (since version 2019.1), but there are unsolved problems with reboot after petalinux was started. Therefore this change is canceled. Only modules where other than S25FL256SAGBHI20 was used are changed to S25FL256SAGBHI20.
Impact: Jedec Manufacturer ID is 01h, the device ID 0219h. Size does not change, 256 Mbit flash are available.
#3 Clock Revision Change (U9) SiT8008AI-73-XXS-25.000000E to SiT8008BI-73-XXS-25.000000E
Type: BOM change
Reason: Switch to actual revision. Revision A devices may be discontinued.
Impact: None.
