20 Icarus to one 650W ATX power is better. Icarus to abcpool bitcoin 12V yellow cables.
If you have more Icarus like 40. Cables link: ATX cable 1 ATX cable 2 Power cable 5. Burned bad quality cable, it should be 4 yellow cables and 4 black cables. Burned power adapter, the case became uneven. Icarus connect to this power adapter not broken.
PWR_OK: power modules output are all in good voltage. TXD1 and RXD1: for display transport on the USB UART bridge, but by a design miss, they are difficult to discriminate, and this function is also implemented on other LEDs, so will be removed in the future. LED1: FPGA1 is busy, in the origin bitsteam, light means FPGA is working, but it changed to opposite. LED4: valid nonce found by FPGA1. LED8: valid nonce found by FPGA2. PC, it recognized as a ttyUSB device or COM on windows PC.
Send back the results if the fpga found a valid nonce, they will send back the 32bits nonce result immediately. Send a work pass the COM port, start a timer and a listener on the COM port. If any data send back by the COM port, then this is a valid nonce. FPGA and send the result back to the pool. If no data send back in 11. FPGA will start the calculate when you push a work to them, even they are busy. The 2 FPGAs on one board will distribute the 32bit nonce to calculate.
FPGA will stop work when: a valid nonce has been found or 32 bits nonce range is completely calculated. 2 FPGA both find valid nonce in the meantime, the 2 valid nonce will all be send back. 0 once it gets to the end! 0 VERY quickly we know it is a real nonce or if the FPGA can send back a “I’m done” message, it would probably make it easier to do more efficiently.
FPGAs on the board and their speeds. FPGA if it gets too hot, need additional hardware. Written with C, support long polling and rolling time. Setup with Icarus, connect Icarus to your PC. Icarus, –api-network –api-listen is for API access for miner. P2Pool is no good with FPGA coz of 10s LP, check out those 1 2 for more detail. WAN port of the TL-WR703N and acquire an IP address via DHCP.
It should come up under the 192. 5 seconds for cgminer start the API thread. Icarus count, if the Icarus count is not correct, you can restart he service again. Utility give 0, didn’t upload works to pool. USB HUB between 703N and Icarus or use a different power adapter like 5V,2A or 5V,4A.
If the elapsed give ‘2XXdays ‘ because the ntpd service start after cgminer. A 13 ports usb-hub, you will need that when you connect more Icarus. WAN port of the TL-WR703ND and acquire an IP address via DHCP. Modify base on Open Source FPGA Bitcoin Miner. 03-SP2 for get the final result. First synthesize the stuff under . Implement Top Module, then you got a NGC file, named sha256_top.
PrjPCB by Altium designer 10 to browse. Make sure total 15 libraries are imported, see compiled libraries and S61. You need install the ISE 13. 1a schematic but pcb buttom side rev. U3, U4 footprint does not coincide with Winbond W25Q64CVSSIG’s 8-SOIC.
