Question about the hello program

kaihsin · May 11, 2017, 5:51am

I use vmware to install ubuntu 16.04 and follow the instruction within the start guide.

make software PROGRAM=hello BOARD=freedom-e300-hifive1
and the binary is built successfully
make upload PROGRAM=hello BOARD=freedom-e300-hifive1

Successfully uploaded ‘hello’ to freedom-e300-hifive1.
It seems that the upload is also successful.
I expected that the terminal which open /dev/ttyUSB1 will show "hello world"
But it still show

/cs-v1/;
/{
model = “SiFive,FE310G-0000-Z0”;
compatible = “sifive,fe300”;
/include/ 0x20004;
};
this is a test

Could anyone give suggestion?
Or Does the printf transmitted the anohter uart pin:GPIO 16 17?

I reported the same problem with the Arty here, but have not seen any response yet. My guess is that a bug has been introduced into the most recent toolchain on git.I got this problem only after updating the toolchain. Despite what the output is saying, the upload does not at all appear to have been successfull.

Hi guys, Thanks for reporting this.

I have just confirmed that things work properly with the binary toolchain distribution here (though you will have to edit the make file to point to the correct binaries:

I’ll compile the toolchain in freedom-e-sdk to see if I can reproduce.

dgrubb · May 11, 2017, 6:10pm

I can’t comment on why, but the problem appears to be somewhere in this commit:

I rolled back my checkout of openocd and rebuilt the tools:

dave@Arthur:~/Projects/freedom-e-sdk$ cd openocd/
dave@Arthur:~/Projects/freedom-e-sdk/openocd$ git checkout fa8d7adf33

After which things started working again.

dagema · May 11, 2017, 7:25pm

Thanks Dave, I’ll try that as well.

HI all

I use git revert to abandon the change “allow all hart to be reset” and rebuilt the tools.
But I encounter the below errors.

HI All

I know the reason.
I have to install libexpat1-dev then rebuilt the toolchain.
Now I can upload the software.
But I can’t run with gdb.
When running the gdb, I encounter the error as below

kaihsin@ubuntu:~/test/freedom-e-sdk$ make run_gdb PROGRAM=dhrystone BOARD=freedom-e300-hifive1

Are you also running openOCD in another terminal:
make run_openocd PROGRAM=dhrystone BOARD=freedom-e300-hifive1

gdb has to connect to openOCD to talk to the hardware.

kaihsin · May 15, 2017, 1:17am

HI Drew

Yes. You are correct.
Thanks for your help

dgrubb · May 15, 2017, 9:26pm

Looks like a fix has just been checked in.

Smooth.
