Burning eFuses to start from HyperFlash #168

Closed plat-zhaw closed 3 years ago

plat-zhaw commented 4 years ago

Hi,

I am trying to boot the GAP8 on a GAPuino V2 from the HyperFlash. Do do that I need to burn the rights eFuses. According to the documentation of the gap_sdk release 3.7.1 i tried to do that. But i will not work.

Here is the terminal output:

(base) immanuel@ubuntu1-VirtualBox:~/Documents/GAP8/gapuino_v1$ openocd-fuser-hyperflash BE CAREFUL: This will permanently configure the board to boot from hyperflash and cannot be undo. Do you confirm (y/N) ? y Configuring board for hyperflash, please stop it when "fuse_once is done" is displayed.

Thanks for all the help.

Hi,

Due to the last release, I think there are 2 parameters are necessary for the fuser haven't been configured by default. Could you please do: export OPENOCD_CABLE=interface/ftdi/gapuino_ftdi.cfg export OPENOCD_CHIP_TARGET=target/gap8revb.tcl

Then retry the script?

Best

Hi,

I very much appreciate the fast answer.

I did as you suggested but unfortunately it did not work.

Here the terminal session:

EDIT: I just opened an other terminal session and source configs/gapuino_v2.sh and checked the environmental variabled OPENOCD_CABLE and OPENOCD_CHIP_TARGET and they already have the right value as asigned by the two eyports you suggested. So that seems not to be the issue here.

Thanks for your help.

Best regards Immanuel

Yaooooo commented 4 years ago

Em...It seems you (the script) are not using the right openocd. Could you please try: which openocd and which gap8-openocd

If the one, gap8-openocd is point to: gap_sdk/install/workstation/bin/gap8-openocd Then please change it in the script, line 9, the openocd -> gap8-openocd

Best, Yao

plat-zhaw commented 4 years ago

I did as you suggested:

(base) immanuel@ubuntu1-VirtualBox:~/Documents/GAP8/gapuino_v1_2$ which openocd /usr/bin/openocd (base) immanuel@ubuntu1-VirtualBox:~/Documents/GAP8/gapuino_v1_2$ which gap8-openocd /home/immanuel/gap8v2_sdk/install/workstation/bin/gap8-openocd (base) immanuel@ubuntu1-VirtualBox:~/Documents/GAP8/gapuino_v1_2$ which openocd-fuser-hyperflash /home/immanuel/gap8v2_sdk/install/workstation/bin/openocd-fuser-hyperflash

Now I do not know, if that is correct or not. And to which script are you refering to? To the this one /home/immanuel/gap8v2_sdk/install/workstation/share/openocd/scripts/target/gap8revb.tcl?

Yaooooo commented 4 years ago

Sorry for my un-clear explanation. It's the /home/immanuel/gap8v2_sdk/install/workstation/bin/openocd-fuser-hyperflash

But just fyi, this path is the script where has been "installed", if you want to change from the source, you can find it here: gap_sdk/tools/bin

If it works, please let me know, I will tag this as "bug" and push a fix in the next release.

plat-zhaw commented 4 years ago

Now I understand it. So I changed line 9 in the script openocd-fuser-hyperflash from openocd -f $OPENOCD_CABLE -f $OPENOCD_CHIP_TARGET -f tcl/jtag_boot.tcl -f tcl/fuser.tcl -c 'fuse_hyperflash_boot '${GAP_OPENOCD_TOOLS}'' to gap8-openocd -f $OPENOCD_CABLE -f $OPENOCD_CHIP_TARGET -f tcl/jtag_boot.tcl -f tcl/fuser.tcl -c 'fuse_hyperflash_boot '${GAP_OPENOCD_TOOLS}''

It did seem to help some. Here is what I get now if I execute it again:

(base) immanuel@ubuntu1-VirtualBox:~/Documents/GAP8/gapuino_v1_2$ openocd-fuser-hyperflash 
BE CAREFUL: This will permanently configure the board to boot from hyperflash and cannot be undo. Do you confirm (y/N) ?

Configuring board for hyperflash, please stop it when "fuse_once is done" is displayed.

So now it finds the chip and tries to do the burning. But I do not get the "fuce_once is done" message. Instead it just repeats the message "Warn : Burst read timed out" over and over. So I assume that the fuse buring did not work. But I will try to load a simple LED toggling into the hyperflash and see if the GAP boots from the hyperflash.

After that I tried loading the image into the hyperflash on my GAPuino V2:

Once again I get the message "Warn : Burst read timed out" over and over. After a while I terminated the script in the terminal. Then I disconnected the board from the USB and reconnected it. The user LED does not blink. I pressed the reset button on the board and still the LED is not blinking. So I assume that either the burning of the fuses did not work or the loading of the flash image file did not work. I do not know which is the problem.

Is there a way to read the eFuses and display them?

So now I tried to build and program the same example over the JTAG interface from the computer:

As you can see I get a warning that the CRC is wrong. And the LED is not blinking so it is not working. I have no idea what is going on. I just hope I did not destroy my GAPuino board.

Since I have two GAPuino V2 boards I loaded the blink_led example onto the second board on which I did not try to burn the fuses to boot from the HyperFlash. On that board it is working just fine:

     *** PMSIS Blink LED ***

Entering main controller
Blinking USER LED

The user LED is blinking as it should.

It is my understanding, that after burning the fuses to boot from the HyperFlash it should still be possible to boot from the JTAG interface and load a program from there. Am I wrong? Did I destroy my other GAPuino V2 board because I tried to burn the fuses to boot from the HyperFlash?

plat-zhaw commented 4 years ago

Soooooo, after some trial and error I got it all working.

  1. If you terminate a process in the bash using Ctrl+Z, because it does not react to Ctr+C, it does not kill the currently in the bash terminal running foreground process. All Ctr+Z does is giving control back to the terminal. So after you did that you need to kill the still running process(es) using kill -9 . I know this does out me as a Linux noob ;-) But there might be other who do not know that. So I thought it worth mentioning.

  2. When I tried to burn the eFuses to boot from the HyperFlash I had the Himax camera connected to the GAPuino V2 board. Apparently that is not a good idea. I disconnected the camera and I could load the blink_led over JTAG again. Furthermore, I get a lot less warnings "Warn : Burst read timed out". See my console output for loading blink_led over JTAG:

3. After that I tried to burn the eFuses again. This time I left the camera disconnected and low an behold the burning worked:

This time I still got a warning "Warn : Burst read timed out", but just once.

4. Having burned the fuses I recompiled the blink_led example:

5. Then I flashed the above built image:

flasher is done!


It worked! After the flashing of the HyperFlash the user LED started blinking. The I pressed the reset button on the board and the LED started blinking again, without having to load the program over JTAG again. After that I disconnected the GAPuino V2 board from the USB (and therefore removed the power supply). After plugging it in again the GAP8 booted nicely from the HyperFlash and the user LED began to blink.

**Conclusion:**

There is a bug in the openocd-fuser-hyperflash script on line 9. There, openocd has to be changed to gap8-openocd. The same bug is in the scripts openocd-fuser-fll-revb (same line) and openocd-flasher (line 10).

To burn eFuses you should not connect anything to the GAPuino board and it should work.

There still does appear to be a problem which prompts the display of the warning "Warn : Burst read timed out". The people from GreenWaves might want to look into that.

Thanks a lot to Yaoooo for the help.

Glad you find out the problem! I reopen it for us to track there is a bug fix need to be done.

For what you mentioned disconnect the camera, I found it's very strange. I don't think this will cause the fuse failed. Will double check it. Thanks

plat-zhaw commented 4 years ago

Of course I am OK with you reopening the issue. I just thought I was supposed to close it, since I was able to get it running.

About the camera: I am not sure the Himax camera was really the problem while burning the eFuses. What I can tell you is that after I disconnected the camera it worked. But that might also be, because that time around the GAPuino was disconnected from the power supply longer than before and that might have given all the capacitors more time to discharge and therefore it was a "more complete" reset of the whole board. What I can tell you with certainty is, that if the camera is connected, I get a lot more warnings "Warn : Burst read timed out" than when the camera is not connected. That is for just loading some program over JTAG unto the GAP8. I think that is also very odd and I have no idea, why that is the case. As said in my (not anymore) closing post you (or some other engineer from GreenWaves) might want to investigate this warning message. For now they just might confuse people, which are new to the GAP8 universe and do not know that this is kind of normal.

Please do not hesitate to contact me, if you have further questions or you need me to try something out for you. I am happy to help in any way possible (as far as it is in my not so considerable power).

Hi @Yaooooo, in the current SDK version this bug is still present, are you planning to include a fix in the next release?

Best,

Manuel

Yaooooo commented 3 years ago

Efuse tool has been updated. In the latest release, you can find this tool: https://github.com/GreenWaves-Technologies/gap_sdk/tree/master/tools/gap_fuser It should be much faster and easy to be used.
