imx6 jtag random Invalid ACK (7) in DAP response

Hi everyone, I'm still picking at the mazda cmu and I've already been able to connect to jtag, but there's a problem. After initializing the memory, the chip stops responding to jtag commands after a while, and openocd resets the connection accordingly. If I do everything quickly and try to download the compiled project from eclipse, I get a bunch of:

Error: timeout waiting for DSCR bit change
Error: Error waiting for InstrCompl=1
Error: Error waiting for cortex_a_exec_opcode

and the subsequent loss of communication. I tried initializing the APB-AP registers with the command imx6d.dap apcsw 1 0 and disabling wdog, but it didn't help. I have attached archive with my configs and log.
