ECOs

• places C56 across U21 pins 3 and 4. (478-9265-1-ND)
• C55 C58 removed
• C608 placed at C35's location
• Wire from Zynq POR R230 to U209 pin 7 @R356
• Change R257 to 5.1k and R258 to 12k (further fix with either new U209 or resistor divider on both inputs of U209) (U209 diff inputs only work starting at about 1.3V, not 3.3 doh!) Possibly switch to using a TPS3895 for power up.

Power up

• Nothing installed: 48V @ 0.06A (1A trip, 0.5A limit)

3V3 STBY OK

• Adding 12V en jumper: 48V @ 0.12A (same trip/limit)

3V3 STB OK

12V OK

• Changing CLPD JTAG port to local power for test. (swap R640 & R641)

Yay! the CPLD came up on the boundary scan

Moving the CPLD JTAG back to Zynq

New IPMC FW

• IPMC didn't explode.
• Seems like the blue LED is red...
• Adding ESM for network access

• 2020-10-08
• latest fw isn't working, going back to modified no shelf FW
• IPMC FW with 12V on gives 0.13A on 48V
• ESM required ECO to pull EN high (connected it via R249)
• networking not working. Unknown.
• try to power up zynq supplies via wire between R208 and 12V (proper turn on for 12V->4.5/3V converter)
• with this installed all misc and zynq 4.5,3.0,3.3,1.8 supplies come up. ~370mA

Booting 7 series Zynq

• Powered up with FW. Using 0.43A on 48V

Si 5344

• SCLK AND SDA were swapped, fixed in FW
• xtal was installed incorrectly
