i restore original t9+ firmware but what realy happened to my miner
what you think? i try to revert back to original firmware but fails
Anyone ever get their T9+ with this issue fixed? I've been searching without any luck.. My T9+ was working fine on the latest official firmware from bitmain's site but I made the mistake of downloading the source code which I saw was a year old but figured not a big deal since it specifically supports T9+. I set miner type for T9+ like build instructions say (it defines T9_18 in the header file),
CHANGED NOTHING ELSE, built it, uploaded to my T9+, killed the running stock bmminer, & ran my built copy & bam now I got these same "failed on chain" errors. I never installed the Dollemizer or taserz firmwares btw.
I had happened to be running the new build in screen session so I could watch what was happening & it was flipping out with those failed on Chain errors then "chain[1] PIC need restore ..." 3x each for each chain in succession but bitmain's dead miner detection kept kicking in mind reflash of the PIC's causing reboots so the process would start all over again. The problem boards seem to show "Check chain[2] PIC fw version=0xff" vs the working boards seem to show "Check chain[3] PIC fw version=0x90" (ff vs 90). Logs show other things like
T9+ try get asic num for the 2 time Chain
[J2] has 0 asic
set_reset_allhashboard = 0x00000000
T9+ try get asic num for the 6 time
Chain[J2] has 0 asic
Chain[J4] has no freq in PIC, set default freq=200M
Chain[J4] has no core num in PIC
Chain[J13] has no freq in PIC, set default freq=200M
Chain[J13] has no core num in PIC
Chain[J14] has no freq in PIC, set default freq=200M
Chain[J14] has no core num in PIC
Pretty sure that's not a good sign.. lol Btw I have them underclocked at 200mhz in conf file.
In between reboots (and hoping the newer factory original bmminer would repair the boards), I renamed the factory bmminer back & upon the next auto reboot the new one ran up but unfortunately as others have found some of my chains are dead/missing still. Only chains 4 13 & 14 are working so my hash rate is awful. Whopping 1213 GH/s at 200mhz lol
So far I've tried factory reset & flashing the older autotune T9+ stock from bitmain with no luck fixing it. I ended up modding the source code I had downloaded to skip the PIC writes to see if the build at least worked & it does! Other than Temp(Chip 1) which is normally just - (dash), now shows a negative value like -23 etc which is odd.. Temp(Chip2) shows what appears to be about right for temp. Since I defined T9_18 per the docs it's as if some parts of the code are ignoring that & building for the wrong model or something.. That would explain the PIC errors & corruption as well if that were the case.
Unfortunately I can't find newer release of the source code to try building that and I can't find the older pre-autotune firmwares to try either so I'm kinda stuck. I found this thread with multiple people with this error & hoped to find a definitive fix before I tried anything else. I read thru all the posts & didn't see any solutions so any insight on fixing this issue is appreciated.
Thanks,
Bill
