2012-07-27 01:02 <kristianpaul> xiangfu: Hi
2012-07-27 01:04 <kristianpaul> how much current drags the slx9 board as it is right now?
2012-07-27 01:07 <xiangfu> kristianpaul, how do measure it?
2012-07-27 01:10 <xiangfu> kristianpaul, I have a multimeter
2012-07-27 01:11 <kristianpaul> you need tap your main powesupply source
2012-07-27 01:11 <kristianpaul> and set multimeter to Amps
2012-07-27 01:13 <kristianpaul> so one wire from main powersupply yo multimeter and the other wire return to slx9 board
2012-07-27 01:37 <xiangfu> kristianpaul, sorry. the power supply is 5v. then goes to 1.2v and 3.3v. then both 1.2 and 3.3 goes to slx9. then GND back to power supply.
2012-07-27 01:38 <xiangfu> kristianpaul, please give more detail how to do that. should I connect one PIN of multimeter to 5v+? then?
2012-07-27 01:45 <kristianpaul> 5v power supply (GND) <--->(-)Multimeter(+)---> (GND)SLX9(+)<------>5v power supply
2012-07-27 01:45 <kristianpaul> xiangfu: yes
2012-07-27 01:45 <kristianpaul> 5v or GND
2012-07-27 01:46 <kristianpaul> then back to the slx9
2012-07-27 01:46 <kristianpaul> you tap onw of the two wires that provides the 5V using the multimeter
2012-07-27 01:47 <kristianpaul> either 5v or gnsd wich get esier to you
2012-07-27 01:51 <xiangfu> I connect to 5v+ and 1.2v+. it give 0.1mA
2012-07-27 01:52 <kristianpaul> what about connect between slx9 gnd and power supply gns
2012-07-27 01:52 <xiangfu> wait. it's 0.65mA
2012-07-27 01:52 <kristianpaul> connect multimeter between those two
2012-07-27 01:53 <kristianpaul> hmm and thats "standy" is a bit power hungry.. well thats to be expected
2012-07-27 01:54 <kristianpaul> you could compare later when load a mm bitstream to it :)
2012-07-27 01:59 <xiangfu> what happen if I load mm bitstream to slx9?
2012-07-27 01:59 <xiangfu> I have tried load fjmem to slx9.
2012-07-27 01:59 <xiangfu> since the mm/fjmem bitstream are all for slx45
2012-07-27 02:00 <kristianpaul> but fjmem is intended for flashing a NOR basically no?
2012-07-27 02:01 <kristianpaul> i not sure what will happen.. but there is only way :)

2012-07-27 02:07 <kristianpaul> you have plans for adding peripherals besides jtag? :-)
2012-07-27 02:08 <kristianpaul> guess serial port for a tiny mm soc :_D
2012-07-27 02:12 <xiangfu> yes. or maybe trigger a LED light by jtag.
2012-07-27 02:13 <kristianpaul> ah thats interesting

2012-07-27 10:37 <hellekin> today I will meet people from Intel Brazil.
2012-07-27 10:37 <hellekin> I already made contact with the marketing director of CEITEC, the Brazilian chip fab.
2012-07-27 10:38 <hellekin> Both companies were quite surprised with the concepts I proposed them, and also interested. They probably don't have many people offering them to change the world by helping their competitors.

2012-07-27 16:26 <Ayla> do you guys know how I can power off the device from a non-linux code? (from a bootloader actually)
2012-07-27 16:29 <Ayla> I'd like the bootloader to power off the device if there's an error
2012-07-27 16:32 <whitequark> yeah. check the jz4720 manual on power management
2012-07-27 16:33 <whitequark> you'd need to turn off backlight GPIO and put the CPU in the deepest sleep mode
2012-07-27 16:35 <Ayla> that's enough?
