Could you provides openFPGALoader version and your setup (computer/SBC and OS).
The first result shows an align error: it may appear sometime when using fly wire but with an onboard interface it's a bit weird.
Could you try to sudo modprobe -r ftdi_sio
?
Maybe a dmesg
dump will be useful.
Thanks
$ openFPGALoader -V
openFPGALoader v0.7.0
sudo modprobe -r ftdi_sio
didn't give any output.(...)

You use an intel x86 64bits computer: I have not seen issue in this situation (I have seen issue with some ARM boards).
Sorry my question was not clear: sudo modprobe -r ftdi_sio
is used to remove driver used for FTDI devices. You must retry to load bitstream (Could you try in a first time to load into SRAM?) and after then make a dmesg dump.
v0.7.0 is quite old (9k support was added after this release): could you try with master branch ?
Thanks.
"Could you try in a first time to load into SRAM?" - yes, I have already tried...
I will compile from source and try again with the newer version
loading to SRAM is working or same issue appear?
I compiled from source again in a new Manjaro with kernel 5.15.60-1-MANJARO
I am going to make the same procedure and paste the output here
I have installed Manjaro in a brand new native machine and I have got the same error: openFPGALoader version:
I have also added the 99-openfpgaloader.rules
from the repository folder using the command:
$ sudo cp 99-openfpgaloader.rules /etc/udev/rules.d/
considering that my device access group is not dialout
neither plugdev
groups, but root

Criação: -
the only modification I did in 99-openfpgaloader.rules
was to edit the group id from plugdev
to root
, and added my own user to that group:
# Original FT2232 VID:PID
ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", MODE="664", GROUP="root", TAG+="uaccess"
I ran:
$ sudo udevadm control --reload-rules && sudo udevadm trigger
$ sudo usermod -a $USER -G root
and then tried to flash to SRAM, but what I have got is:
Now my machine specs are:
Ok: your previous error seems due the rules configuration (using root group may be not good for security). Now problem seems related to communication: it's weird because openFPGALoader is working with the BL702 (I use it with tang primer 20k) but I think I have to bought a 9k and trying with a second computer I have with archlinux to see if it's related to the OS/kernel or something else... Have you another computer to test? Some people have reported wrong/good behaviour according to hardware (mainly with the ch552 used for first tangNano board).
I am aware of the risks of using root permissions in that case, I only want to know what is going on.
I have also tried to use the official gowin programmer but I could not detect the board either....
I will try to test it in another computer, but I am not so confident because I have got the same issue from an entire brand new machine with manjaro linux installed (I have also had problems with Ubuntu 22.04 LTS, too)
Problem solved by using a second computer with MS Windows and GoWin Official Programmer as admin by erasing SRAM and embedded flash.
I could flash the example project in the embedded flash memory using the second PC.
The FPGA has successfully presented the led demo, so I went back to the original linux machine and used openFPGALoader
...
This was the result I have got in the manjaro linux machine:
I did not make any configuration change from the last unsuccessful flash, just erased SRAM + embdFlash and come back again to original PC, I don't have idea what was the big deal so far to disable the flashing from linux.
but now it is working! Thanks to @trabucayre attention
closing the issue...
Maybe it's related to the reboot: when you update user group for a user you have to logout and login again... Or simply reboot the computer. Thanks!
Is there not a way to erase this flash/resolve this issue without a windows device? I don’t have any available currently.
Have you experimented the same issue recently? This issue is a bit old and outdated. Gowin's driver have received lot of improvement.
I had a very similar sequence of problems, I think it started with my incorrect rules for the USB port and at some point
I got mpsee_read/mpsee_write()
errors as above. I followed advice of @Chandler-Kluser : on Gowin website one can
download "Programmer" soft (Educational Version) and it has commands Erase SRAM, Erase Flash memory.
After erasing and setting rules for USB as advised on Sipeed website it works correctly now.
Thanks for your feedback. I have to see why doing the same thing with openFPGALoader.
To my previous post - using Gowin Programmer did not do any help CRC errors and FTDI ones were appearing very randomly so for my case I cannot say that it was a solution.
@trabucayre @Chandler-Kluser After two dense days I found that my Tang Nano 9k is flashed perfectly fine 100% of times if ....
I simply use the original usb-cable from the little box how it is shipped, otherwise - CRC errors / and further problems with FTDI drivers. So my advice would be try to simply change the USB cable to original one and ensure that the board is accurately isolated (in my case I pinned it to my breadboard).
I have no idea what had happened ..... But possibly it is just a hardware issue - again using original usb cable solved all problems magically....
Yes cable is an usual case of failure. For isolated board: one possible thing (not limited to this board) may be related to the computer with or without ground pin. Also sometime USB interface contains an isolator (or something similar) just after usb connector. Using a short cable may reduces some ECM issue.
I cannot flash my Tang Nano 9K with a default led example project provided by Sipeed.
I have fully compiled the bitstream file and used openFPGALoader to write to flash memory:
I have read issues #245 and this question from Stack Overflow, my user has all permissions to access FTDI device, which is listed by:
Here it is my rules.d file for this device:
This error happened only once, and then I couldn't even access the device anymore:
Neither with root priviledge:
Is there something I missed? Thanks in advance!
