HEX file to get programmed; the 2nd stage: click connect to connect Ordinarily; the 3rd stage: simply click This system button, and after completion, click on verifiy to prompt the verification to prove the programming is effective.
Repair approach: Verify the appearance, evaluate the chip capacitor or resistance in front, typically It is brought on by poor chip soldering or possibly a chip capacitor, resistor damaging or abnormal resistance; VI. Control Board Issue Causing the next Challenges 1. The full miner does not operate one) Look at whether or not the voltages at many voltage output factors are normal. U8 might be disconnected very first if three.3V is short-circuited. If it is still brief-circuited, the CPU is usually unplugged for measurement. For other voltage abnormalities, frequently switch the corresponding converter IC. two) When the voltage is usual, you should Verify the welding standing of the DDR/CPU. three) Attempt to update the flash software with SD card; In case the miner of which the Handle board has been reflashed has to start off Generally, the subsequent two actions are needed: a) After the card Restoration is handed, the inexperienced LED indicator will probably be constantly on, and the power shall be restarted; b) Await 30s just after powering on all over again (time training course of turning on OTP).
When the miner whose Command board is flashed really should start off Usually, the subsequent two ways are necessary:
As outlined by this technique, discover the chip that still has the long-tem working failure immediately after a certain chip is short circuited. Commonly, it's due to a specific chip damaging, so just replace it; Figure 5-19 7. Phenomenon: PT1 chip test is Alright, PT2 operate exam often experiences a specific chip NG.
8V and 1.2V patch filter capacitors are limited-circuited, or maybe the IC with the LDO circuit During this area has weak soldering/Phony soldering/material injury;
Pattern NG is a result of the large distinction between the traits from the chip and various chips. At this time, it truly is found which the chip die is damaged, so just substitute the chip. According to the log information, the substitute principles are as follows:
two. Make the SD screening card As outlined by the requirements, and specifically unzip the compressed offer of the single-sided heat sink inspection chip to create the SD card;
The repaired hash board may be judged as a fantastic product or service with much more than two passes when tested Using the hash board tester.
37V. This example is attributable to Order Here the chip not remaining soldered appropriately, generally 1.2V, 0.8V, RXT, CLK will not be soldered adequately. It is usually recommended to right measure the domain voltage to Track down the problematic area. The 1V2 and RO small circuit process used in area a) can also Identify the abnormal place
minerstat is not only An additional calculator - It truly is a powerful mining platform that supports your copyright journey. Increase your revenue, help save beneficial time, and optimize effectiveness with our suite of high quality characteristics:
d-1) The first scenario: the check time is largely similar to The great board (typically the worth of X will never alter every time you examination) (test time refers to the time from when the start take a look at button is pressed to the result of ASICNG: (X) displayed over the LCD).
minerstat isn't just A different calculator - It is a powerful mining platform that supports your copyright journey. Strengthen your revenue, help you save useful time, and increase performance with our suite of high quality attributes:
Repair method: Look at the appearance, measure the chip capacitor or resistor in entrance, it is frequently a result of weak soldering of the chip or even a harmed chip capacitor or resistor or abnormal resistance benefit;
The voltage of each voltage domain is about 0.36V. When there is 14V electric power supply, commonly it's got area voltage. The precedence is presented to evaluate the output of the facility offer terminal from the hashboard and whether the MOS is short-circuited (evaluate the resistance among pins one, four and 8). If 14V has ability supply but no domain voltage, continue to examine.
