1  Bitcoin / Mining software (miners) / Building Bmminer from Bitmain's Github on: May 20, 2018, 10:04:23 AM
Hello all
Sorry for the noob question.
Could you please share some info regarding building Bmminer?
_---------
environment setup:
need 2 PATH: toolchain base path and other open source lib binary and include files base path.

for example:
XILINX_BASE_PATH=/ho
me/XILINX/gcc-linaro-arm-linux-gnueabihf-4.7-2012.11-20121123_linux
XILINX_OTHER_LIB_BASE_PATH=/home/XILINX/bin
--------------

I did get gcc... forXILINX_BASE_PATH , but I have no idea what files go into XILINX_OTHER_LIB_BASE_PATH.
Can you ,please, tell me what to include in this folder?
I am trying to build on a Linux Mint machine.

I have done linux builds of cgminer following guides before, but I never tried to crossbuild on linux for different distributions before.

So better, a little tutorial for me and everybody who needs it would be great if some more savy people have the time to write-up.

Edit: see post 12 for the tutorial link.

Beat regards, Mihail

Salutari,
Cine are aparate minat defecte?

Pot oferi ajutor Ón repararea minerilor.
Locatie: Navodari, jud. CONSTANTA

 Am experienta cu Gridseed Orb si Gridseed G-blade.
Edit1: + experienta cu Antminer S3 si Zeus miner.
Edit 2: + experienta cu Antminer S5  si S9

18.04.2018- stoc de piese de schimb originale provenite de pe hashboards de Antminer S3, S5 si S9-autotune.
Placa de S9 are un singur cip defect, restul sunt ok.

Va pot ajuta cu urmatoarele:
 -Controller : reparatie, debrick-uire, update firmware...
 -Unitate: reparatie hashboard ( inlocuire cipuri), curatare, inlocuire mufe alimentare...

Oferta curenta:
1. Puteti veni personal sau trimite aparatul prin cineva de incredere pentru a vedea unde locuiesc si pt a face cunostinta. Accept si semnarea unui document care va mentiona ca ati lasat aparatul defect temporar in posesia mea. In schimb, rog sa postati aici pe forum parerea dvs la sfarsit pt ca si ceilalti forumisti sa poata citi.
 2. Diagnosticarea gratuita. De asemenea, daca nu se reuseste reparatia, nu se taxeaza (+retur pe costul meu daca e aparat trimis cu posta/curier)
3. Costul reparatiei se va discuta dupa diagnoza.
4. Aparatul va fi supus unui test de minim 10-12 ore de functionare (la S9 doar placa reparata se va testa).

Atentie: Nu repar surse. Nu repar la domiciliul/locatia dumneavoastra.

   Va rog sa dati PM cu cateva detalii (tip aparat, manifestare defect , nume si nr de contact) si restul discutam fata in fata sau la telefon.

Cu stima,
Mihail
4  Economy / Marketplace / Interested in buying a few dead S9 components on: April 04, 2018, 06:30:06 AM
Hy all,
I am Mihail, I live in Romania and I am an electronics hobyist with board level repair skills(laptops, phones, tablets.. ).
I have been reading many of the topics on this forum and gotta say I am very interested in the technology used in these ASICS.

Is there anyone in EU that has some S9 components (defect ones) that are taking up space and are not interested in fixing them?
I am interested in controllers and hash boards that died while "on duty". Smiley
If you're willing to ship them to RO, I would be available to pay some amount of money for these damaged parts.
I want to study and see if these parts could be revived back to operating condition, but mostly I would use them as " learning material".
I do have experience with older Bitmain products, but I could not find until now any defect S9 components, not here in Romania anyway.
Reading through the topics made me even more curious about the S9 machines, this is why am posting here.
Untill now, only one forum user brought me a defect S9 but we were able to fix it with a firmware upgrade so I did not get to open the machine Smiley.

 Please PM me your offer, if any. Smiley

Happy mining!
Best regards,
 Mihail
5  Local / Market / Interesat sa cumpar hashboard antminer S9 arsa on: February 20, 2018, 07:13:26 AM
Salut, as fi interesat sa cumpar ceva placi arse de S9.
Conditie: placa sa fie completa, fara radiatoare lipsa (chiar daca sunt cazute de pe cipuri dar sa fie in colet).
Sa stiti exact ce tip este (frecventa fixa sau autotune).
Pret: discutabil in functie de aspectul vizual, dar in limite rezonabile. (Trebuie avut in vedere ca e rebut, totusi).

Cu respect,
Mihail
6  Alternate cryptocurrencies / Mining (Altcoins) / zeus thunder x3 voltmod on: June 13, 2016, 07:09:51 AM
Hy all,
Can anybody who owns a Zeus miner Thunder X6 make some closeup pics of the power chips area, please?
I am interested in the values of the resistors situated between the 2 big chokes and a pic of a power chip area resistors. Please make the picture so the resistors writing can be visible...
-edit- 1:pics no longer necessary; 2:subject name changed

Very usefull would be ,if anybody knows what buck controller chips are used on these boards, to post the chip serial number here.


I am asking for this info because I have bought a defect Thunder X3 from a fellow forum user, and after studying the boards and the hash chips datasheet, I noticed that Zeus has overvolted and overclocked these X3 chips to their (allmost)max values from factory... I am thinking that the ThunderX6 is only a slightly overvolted unit, and would like to undervolt my X3 to those values or below if possible.
 This would also be usefull info to those how want to overclock / mod/ service defect units... etc.
 After I am finished repairing and modding this X3, I could maybe post a servicing tutorial/guideline for these units. (I have managed to fix 3out of 4  hashing boards of this unit and now working on the last one. )

Thank you!

Salut Cryptofreaks din Romania.
 Mihai, 33 ani. Inginer electro/mecanic si electronist din Navodari, Constanta.
 Am auzit de Crypto mai demult dar nu prea am fost interesat pana acum vreo 2 luni cand am avut ocazia sa cumpar niste mini ASIC-uri ieftin(unele defecte). Am reparat pe cele defecte apoi le-am modat pentru consum minim (bine, si hashing minim). In prezent  minez cu aproximativ 6Mh scrypt. O fac doar din curiozitate. Smiley
 Am intrat in comunitatea crypto mai mult pentru ca tehnologia/tehnica mi se pare foarte interesanta si sunt curios sa vad si alte aparate de minerit.
Nu am de gand sa ma las de servici pt asta, dar fiind in faza de invatare, sunt dispus sa incerc sa ajut.
