Try to use Latest EasyJTAG Classic software and choose different VIO settings
Also you can use HiPower CLK mode with USB-powered board (connect onli GND/CLK/CMD/Dat_0)

I had the same problem with the a105f device with easy jtag plus the solution was done by connecting a resistance of 100 ohms between the vccq line and the cmd line and choosing the frequency 9mhz or 1mhz
note: i do not have an isp adapter i use direct connection to the box and in this case i connected the power vcc and vccq from the box and not From usb, you have to try and try to find the solution.
also in my case the emmc was corrupted
