A repository trying to make ant miner T9/T9+/S9 run OpenWrt
T9/T9+/S9 control board has very similar layout .Which the firmware can be compatible!
| Part | Detail |
|---|---|
| CORE | XC7Z010 (Y) |
| RAM | 512M*2 DDR3 (Y) |
| ROM | NAND FLASH 128M(N) |
| Ether | B546512e,B50612e/d(Y) |
you will need to replace uboot.bin+system.bit+u-boot.img unzipped from braiins-os after u use rufus to write the OpenWrt firmware to sd card

Back in 2020 I accidentally received some broken Ant Miner t9+, A ASIC Miner got ZYNQ XC7Z010 init, and I want them to have some extra usage for so hard!! So I was thinking about OpenWrt. but the advanced firmware structure of ZYNQ beat me (I only had Android building experience back then). QAQ In 2023 after 2.5 years, I saw a news on my smartphone it was about OpenWrt .this made me recall my scraped ASIC miner. this time I have some more experience from building a few smartphone kernels and a few failed x86 Openwrt build.
the hardest part was porting the .dts for Openwrt from braiins os seems that braiins os made some changes to their kernel to make the 5.10 kernel "fully" support the 4.4 kernel .dts structure for zynq on the 5.10 kernel. if you try to build openwrt with old structure .dts the internet bridge Ic won't able to find driver for itself (what I think the reason why internet bridge Ic not working is because "emacps.c" got deleted from 5.10 kernel) so I start to port from a similar device already supported by OpenWrt the structure of them, and they were so different from each other, you simply can not leave them 50% new and 50% old. after porting the problem coincidentally back to the internet bridge Ic. I was guessing that caused by RGMII BUS or device id of Boardcom B546512e,B50612e/d address incorrect or maybe that kernel doesn't even support Boardcom B546512e, B50612e/d, then I started with the simple one. changing the RGMII interface address and hope it works, what I was using is the address from the dts. inside the UBOOT source code but I found that source code from braiins os has two different RGMII interface address one from the .dts inside UBOOT and it was 0x07 another one from kernel was 0x01 .so I change it from 0x07 to 0x01. this time, I finally got a 3 years project basically working
!The evidence of they were so different!
