Follow up to https://github.com/sifive/freedom/issues/127 . I have successfully build and uploaded Freedom E300 on my Arty Rev. C board using Vivado 2018.3. OpenOCD can detect the core but when I send telnet command to it, it returns Error: Target not examined yet

The message you shared looks like normal openocd operation. Its last message is it waiting for a gdb connection.
What are you trying to do with your telnet connection? Could you try doing the same on a gdb connection and seeing if that works?

I use telnet because gdb would not let me connect. Here is the snippet after gdb tried to connect. I call gdb from Freedom Studio and run OpenOCD manually.

I bet the issue has to do with a misaligned .cfg file. Can you attach the .cfg file that you are using to connect OpenOCD, as well as the dts?
nf9

Here they are. They are generated by FreedomSDK. except the .cfg file which I modified slightly to match my adapter. I also commented the halt command to prevent the OpenOCD from exiting. halt will result in Error: Target not examined yet

So it seems like something is wrong with the spi flash device communication, though the address mapping of the dts is in line with what the cfg is trying to access. One possibility is that somehow the fpga bitstream pin constraints are incorrect. What particular fpga board are you using? The freedom-e310 is targeted for an Arty 35T, the 100T might be slightly different pin names.
In the meantime, if you just want to get something working and don’t care about the spi flash chip, you can comment out this line in the cfg file (add a “#” before the line) and I think you should be able to communicate over gdb:
flash bank spi0 fespi 0x20000000 0 0 0 $_TARGETNAME.0 0x10014000

Still no luck. It stops on halt. I also tried it with 2 different Arty 35T boards, Rev C (with Micron n25q128-3.3v flash) and Rev E (with Spansion S25FL128SAGMF100 flash) and the same issue persist. Do you know where I can find the already built MCS file from SiFive? I will try to compare it with the one I built.
