Repair and review of ALTERA Arria II GX FPGA Development Kit (DK-DEV-2AGX125N)

DK-DEV-2AGX125N is a Altera Arria II GX FPGA Development Kit delivers a complete system-level design environment that includes both the hardware and software to develop Arria II GX FPGA designs. With this PCI-SIG-compliant board and a one-year license for QuartusII design software, User has an option to develop and test PCI Express 1.0 (up to x8 lane) designs, Develop and test memory subsystems consisting of DDR2 and DDR3 memory, Develop and test designs based on other protocol interfaces supported by the Arria II GX FPGA, such as Gbps Ethernet (GbE), SDI, CPRI, OBSAI, SAS/SATA and Serial RapidIO (SRIO). Many of these are supported by taking advantage of this board’s modular capability through the high-speed mezzanine card (HSMC) connectors and over 20 different HSMC connectors available through Altera partners.

ALTERA EPM2210 CPLD was dead (internal short), causing 2.5VDC supply to trip OCP. After desoldering this MAX II, power started to work normally, except Arria’s BANK7A supply. That rail is shorted at Arria II chip. :(

FPGA chip is chipped and have internal short. So unfortunaly board is not functional, and PSU repair did not solve issues.
