4 years ago I even built firmware from source and still no-go. Should i try with SD card?

4 years ago This is what it says the first time. Also tried flashing "erase_spiffs.kfpkg" first. No help.

4 years ago I can't reproduce this issue on Sipeed MAiX Dock M1W. Have you made any changes to the sources? Have you tried to flash the prebuilt firmware?
It looks you are not using the kflash.py from this repository, try to use it.
My test with prebuilt firmware:

(pressed **F** on fs error prompt.
How exactly are you "trying to get extra features such as ftp and ota" ?
The repository wasn't updated for some time, but I have a large amount of changes waiting to be commited, I'll do it before Christmas. Among other changes, FTP and OTA will be available in the new release.

4 years ago Hello! Thank you for your response and information. Thanks for all you do and your contributions to the community! Much appriciated, even if I'm not able to get this fw working. Sorry, I thought those changes had already been committed. No worries. Still, your fork is way ahead of official FW (directories in SPIFFS, lol.) and of course I started with the pre-compiled FW! I'm way to lazy to start with compiling.
I did exactly as you instructed (MANY MANY TIMES), both from WSL and actual Debian. The results are the same. Thanks again, but still no go. Note: It seems to "do more" when i choose "E" from the menu.

I will add that through testing I did get this working once - BUT - it would fail to mount every other boot and had no SD Support.
Also, i have only had this board 2 days now. Is it possible they changed something? The "official" fw seems to work fine. Is it possible that it is as simple as needing a delay for the flash to init? Seems like that is possible bc of the intermittent behavior (when the flash does init).
Thanks again! Hopefully you have something else i can try? BTW, I first did all these steps on Tinkerboard running Debian just in case it was WSL causing problems. - same results. I was using kflash before because i could use it within windows without using WSL. Didn't realize they were different. I'm glad that you showed me the "-E" for erase function of kflash.py which is totally missing from the kflash that I was using. If you don't have time to bother with these issues right now, I totally understand. Happy Holidays.

4 years ago This is strange, I've tested it on 4 different K210 board and never had a similar issue. This port uses much higher Flash clock, it may be the reason for the issue (it may be hardware related). I'll try to check the issue more...
Try to flash the MaixPy.kfpkg from
MaixPy_firmware.zipinstead of only the MaixPy.bin. It contains the precompiled file system which will be flashed to the right position so the firmware should detect it at start and not try to format the FS.

['boot.py', 'examples', 'fonts', 'lib', 'www']Do you agree that they probably used a slower flash on the board that i have and that means that it cannot keep up with the fw which has been optimized for faster flash? If you agree, how hard would it be for me to change this setting and recompile?

4 years ago Yes, I think it is a hardware issue.
You can try to change the default SPI Flash clock in k210-freertos/platform/drivers/include/w25qxx.h:
#define WQ25QXX_MAX_SPEED 83000000
Change to 40000000 or 25000000 and rebuild.
Run:
./CLEAN.sh
./BUILD.sh -j8in k210-freertos directory.
Then flash MaixPy.bin.

4 years ago Works perfectly now @ 40000000. Except No SD Card. Do i need to mount SD manually?

4 years ago I'll include the option to set the maximal SPI Flash clock speed in the next update.
SD Card is not mounted automatically, you have to mount it manually. If I remember well, it should be something like this:
import os
sdcard = os.VfsSDCard()
os.mount(sdcard, '/sd')SD card must be formated as fat32.

4 years ago I've tested SD Card support and it works as expected:
>>> import os
>>> sdcard = os.VfsSDCard()
>>> os.mount(sdcard, '/sd')
>>> os.listdir('/sd')

>>> Note: SD card works in SPI mode. Not all SD cards works good in this mode. I've had the best results with SanDisk 8GB cards.

4 years ago Thanks! That was the problem. It wasn't obvious to me that I needed to mount the SD manually since the OFW did this at boot. Great! Glad to have everything working!

4 years ago I was thinking, perhaps you should decrease the SPI clock in your next release for compatibility and allow some users to use an option to increase theirs? I bet most people wouldn't care much and this could cause a ton of issues for people, issues which are hard to diagnose. Just my two cents.
I have tried flashing 3 times and i keep getting this issue: Board: Sipeed MAiX Dock M1W DAN Trying to get extra features such as ftp and ota which are not supported in official fw.
Any Advice?
