| 01:02.37 | kristianpaul | xiangfu: Hi |
| 01:04.14 | kristianpaul | how much current drags the slx9 board as it is right now? |
| 01:07.34 | xiangfu | kristianpaul, how do measure it? |
| 01:10.39 | xiangfu | kristianpaul, I have a multimeter |
| 01:11.20 | kristianpaul | you need tap your main powesupply source |
| 01:11.42 | kristianpaul | and set multimeter to Amps |
| 01:13.30 | kristianpaul | so one wire from main powersupply yo multimeter and the other wire return to slx9 board |
| 01:37.48 | 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. |
| 01:38.19 | xiangfu | kristianpaul, please give more detail how to do that. should I connect one PIN of multimeter to 5v+? then? |
| 01:45.40 | kristianpaul | 5v power supply (GND) <--->(-)Multimeter(+)---> (GND)SLX9(+)<------>5v power supply |
| 01:45.52 | kristianpaul | xiangfu: yes |
| 01:45.57 | kristianpaul | 5v or GND |
| 01:46.02 | kristianpaul | then back to the slx9 |
| 01:46.23 | kristianpaul | you tap onw of the two wires that provides the 5V using the multimeter |
| 01:47.12 | kristianpaul | either 5v or gnsd wich get esier to you |
| 01:51.24 | xiangfu | I connect to 5v+ and 1.2v+. it give 0.1mA |
| 01:52.37 | kristianpaul | what about connect between slx9 gnd and power supply gns |
| 01:52.41 | xiangfu | wait. it's 0.65mA |
| 01:52.52 | kristianpaul | connect multimeter between those two |
| 01:53.38 | kristianpaul | hmm and thats "standy" is a bit power hungry.. well thats to be expected |
| 01:54.03 | kristianpaul | you could compare later when load a mm bitstream to it :) |
| 01:59.19 | xiangfu | what happen if I load mm bitstream to slx9? |
| 01:59.26 | xiangfu | I have tried load fjmem to slx9. |
| 01:59.44 | xiangfu | since the mm/fjmem bitstream are all for slx45 |
| 02:00.03 | kristianpaul | but fjmem is intended for flashing a NOR basically no? |
| 02:01.02 | kristianpaul | i not sure what will happen.. but there is only way :) |

| 02:05.34 | kristianpaul | good |
| 02:07.13 | kristianpaul | you have plans for adding peripherals besides jtag? :-) |
| 02:08.08 | kristianpaul | guess serial port for a tiny mm soc :_D |
| 02:12.10 | xiangfu | yes. or maybe trigger a LED light by jtag. |
| 02:13.41 | kristianpaul | ah thats interesting |

| 16:29.28 | Ayla | I'd like the bootloader to power off the device if there's an error |
| 16:32.45 | whitequark | yeah. check the jz4720 manual on power management |
| 16:33.19 | whitequark | you'd need to turn off backlight GPIO and put the CPU in the deepest sleep mode |
