I can confirm there is an issue with SD and core 2.02:
Core 2.01 reading text file from sd, to be sent to client took 15 ms
Core 2.02 , same task, took 6000+ ms
Needed to go back to 2.01

SD works very slow in 2.02

@AppsByDavideV: It is OK to just remove these lines: f32c0da

Yes, it works fine now with core 2.02, thanks

Likewise, if the lines in f32c0da are removed, SD works in V2.0.2, tested with PlatformIO, thanks to @FrankBoesing

Hello @FrankBoesing, we will take a look on this issue. Thanks for reporting.

Related to #6078. These 2 issues can be validate and tested together, @P-R-O-C-H-Y.

Hello, the same here : SD read and write very slow since 2.0.2. Speed was around 400-500 ko/s before, now 4 ko/s after 2.0.2 upgrade. Thanks

getting random [sd_diskio.cpp:186] sdCommand(): token error [23] 0x4 and [sd_diskio.cpp:174] sdCommand(): no token received under heavy load too.

During a screen capture test, 6 files out of 256 failed to write to SD with an average size of 40kb, this is after applying @FrankBoesing's fix.
