I repeat it there is an error in the source code of bitmain for the T9 +...

what is error in detail you say? are you have solution?

I compiled self-firmware use link: https://github.com/bitmaintech/S9_makepackage for antminer T9+ and S9, then flashing self-firmware to T9+/S9, both T9+ and S9 lost chain. even though I flash to offical firmware through sd card recovery, miners lost chain yet.

hi
i have s9 v4.21 hashboards ...
pic ic need programmed
where can i find pic hex file
thanks

[thierry4wd]

hi, you find this on good working hashboard ...

Sorry i don't have it on my and at this time

[milani1387]

thanks
i i have tnm 5000 prgrammer
i can read hex file from hashboards succesfully.

[thierry4wd]

if you can read the HEX file, you can WRITE this on bad hashboard !!!  

Ps : i have edited my first post with corrected the bitmain source code for never problem with this pic program

[milani1387]

hi. thanks for t9 hex file uploading.

hi guys. is there any option other than flashing the pic with the pickit3?

hi guys. is there any option other than flashing the pic with the pickit3?

If you are looking for another way to write on that digital signal controller or wherever the hex file resides then the short answer is NO, if it's not pickit3 then it has to be another similar tool, but your problem might be solved using another method, post your issue in a sperate thread and you might get some answers.

hi guys
i have 6 T9+ hashboard and all of them have PIC problem

when i try to write hex file i get this error
Too much current has been drawn on VDD. Please disconnect your circuit, check the CLK and DATA lines for shorts and then reconnect.

what should i do with this problem ? i try disconnect and then reconnect

when i try to do read verify or anything like that get this or just failed

when i try to do this work with ok hashboard there is no problem and anything work correctly

my power settings 3.25 circuit from tool

i very need help

[thierry4wd]

Hi, try 3,50V

[KTzMg]

i try it but there is no diffrent

[charcousse]

hola amigo saludos desde acá desde Venezuela... estoy tratando de reparar una t9+ con problemas en placa DSPIC32 y hago exactamente lo que tu explicas paso a paso pero me sale el siguiente error.......

The target circuit may require more power than the debug tool can provide. An external power supply might be necessary.
Connection Failed.     

 
 como puedo solucionarlo gracias de antemano

[thierry4wd]

this is part of the strange errors, which I also had, check all the parameters! chip model in particular ... and try again several times,

I had the same problem, after 2 or 3 or 4 tries, it worked without changing anything ... strange but that's how it's happening;)

Guys clean hashboard Completely and try to write hex file sometimes its Sometimes it answers
