If you are sure the chip is powered and reset properly, It's possible your signal integrity is not sufficient for 25MHz JTAG.

Try increasing the divider:

Code: Select all

 --jtag-speed <n>         Set the JTAG clock speed :
                           XTAG-1 based adapter 6/(<n>+1)MHz
                           XTAG-2 based adapter 25/(<n>+2)MHz
                           (default value for <n> = 0)

We encountered the same problem on our board and we have to power the OTP part even if it is not used to solve it.

thanks for your reply. i find this reason, I2C run on other tile,
on tile [1] : struct r_i2c r_i2c = {XS1_PORT_4E};
