Please answer me.
I have difficulty reading topics with big bold letters, so if you want to get answers to them quickly, then write them in regular font and size

===========
eMMC ISP connection
ISP (In-System Programming) is*not documented connection for*eMMC at PCB. It use 1-dat line (1bit) mode for*transder data between eMMC and box. ISP mode connection use CLK, CMD, DAT_0 (Data zero), GND wires and VCC, VCCQ power wires for eMMC.


Some devices have pads for CLK/CMD/Dat_0 signals*on PCB. But mist devices not have pads, and some devices have no wires for these signals of PCB*top layer (wires are placed at internal PCB layer).


There are 2*types of ISP*eMMC connection:
- Normal mode*
- HiPower CLK*(tm) mode


Normal mode:

At Normal mode ISP MMC connection need use this pins:

GND
CMD
CLK
DAT0
VCC
VCCQ


Device board have no power from USB charger or*battery. Power to eMMC is external (VCC, VCCQ wires) and provide from EasyJTAG Plus box or from third-party power adapder for EasyJTAG 1st generation box.


Some devices need use Pull-UP resistors for DAT0/CMD lines (100-200 ohms)


For best ISP connection relults EasyJTAG Plus box (with box firmware*v2.53+) allow use different VIO levels voltages: 1,8/2.0/2.2/2,4/2.6/2.8/3.0/3.3v

HiPower CLK (tm) mode:
- Device board get power from USB charger or*together USB/battеry.*
- VCC/VCCQ wires are*not connected at this mode.*
- At software must be set "HiPowerCLK mode" checkbox.
- For*EasyJTAG 1st generation box*need use special 4pins CLK adapter.


HiPowerCLK mode is the best solution for most new devices.


At HiPowerCLK mode ISP eMMC connection need use only this pins:

GND
CMD
CLK
DAT0

Important requirements that must be met for a quality ISP connection:
- GND wire should be much thicker compared to others
- the length of all wires must be same
- the length of all wires should be kept to a minimum. Best length*is 5-10 centimeters


CLK clock at ISP mode*determines the data trarsfer*speed beetwin eMMC and box. If the above requirements are met, the stability of operation is ensured at frequencies up to 24-36MHz. The best performance is from 14-24MHz. There is no need to use lower frequencies.*
===========

also you can try change VIO voltage
and change "Disable eMMC hi-speed timing" at software settings

Any reason this should happen? Or is it false positive?
