I have Flipsky 75200 (NOT pro) 75_200_ALU, you have to downgrade to 5.02 or 5.03.
thanks, i don’t find later version of 75_200 than 6.0 (5.03 and previous not available on archive), and no .bin 75_200 on github (only of 75_300 R2). Any idea?
I have installed 75_300_R2. As far I know 75_300_R2 corresponds to 75_200_ALU. I have 75_200_ALU too. I can’t connect to my VESC because Bluetooth module is broken and ESC is enclosed in a waterproof box.
ok thanks, i will also try that. If i have good results with the 75_200 fix noisy i will post, i should be able to test next week . Updating to 75_300 R2 6.5 looks like not a good idea
The problems with higher versions than 5.3 may be related to phase filters. Flipsky was too lazy to build their own binary and get it into the official repo, they just stole the trampa 75300 binary. As of 6.x, the firmware supports phase filters and they are enabled by default. You can disable them in FW. I built a binary for my old Flipsky/makerbase/firduo 75300 with removed HW Filter in the hw definition file and that works well with 6.5 (different hw from yours).
i just disabled the phase filters with the VESC tool. I arrived to open the binary with BinViewer but have no idea where or how to remove the filters…
You can‘t do that directly in the binary, you need to edit the source code from vedders git and then build (compile) a new binary. You need a toolchain for stm32 to do so. That is why Flipsky should do that and provide a matching binary but they are just too lazy. You can also just turn it off in configuration but don‘t forget to disable it again after a fw upgrade!
There are some custom binaries available from the link below but all the different hw version of the 75200 are confusing, so make sure you get the right one: How to update firmware on the Flipsky 75100 & 75200 FOC ESC - The Citadel - Essential References for Esk8 - esk8.news: DIY Electric Skateboard Forums
Might also be included in latest vesc tool.
This is from Flipsky. Their product page(s) also caution about phase filter
Yes, if your HW does not have phase filters
i think to build a source code is out of my knowledge…
i will check the link, it will take a bit time for me to get the right version…
thanks!
