Higher Clock Rate Will Not Work Well With ISP Connection Spsly On 1Bit Connection In Older Devices It May Work But In New Devices It Give Error 18Mhz Is Recommended Speed For ISP U Can Try Higher Clock If Give Error Kindly Reduce Speed If U Want To Work With Higher Clock Better Do Chip OFF N Do Operation Spsly For BGA-254;):) Hope U Got Ur Answer Now

Higher Clock Rate Work Well With ISP Connection Spsly On 1Bit with software old version , this problem only with new update.

brother i wrote "when i downgrade firmware the box is stable in 36mhz" , did you read it ?

Programming is not like cook a hot water to make immediate

Tell your issues and Request solve this as soon as possible.

This is the way of approaching a make changes in Software.

Hope u will understand.

Thank you.

You use incorrect VIO setting and want to normal work?

VIO at most devices is 1,8v

I understand very well what you are saying, but some are not convinced there is a problem, all I ask is that some do the same as my experience and present the result.

I tried all of them 1.8v, 2.8v and 3.3v same result, But with an older version of v3.7.0.20, there is no problem.

you can use older version.
many devices which did not connect by use before, now work.

we most to sacrifice one for the other.

use 24 MHz or try to put a resistor of 20-30 ohm in series in the CLK line

you can also try to "Disable High Speed timing" at settings
