ap6236 bluetooth update fireware always failed

we designed a board base on the imx6ull-14x14evk, and our ap6236 as above images....

pin6----BT-WAKEUP , we pull up to 3.3v with 10K res;

pin34--BT-RST-N, we connect it to gpio1-io18;

first, the wifi of AP6236 is OK, and I use ssh to connect the board with it's wifi.

I do as below:

echo 18 > /sys/class/gpio/export

echo out > /sys/class/gpio/gpio18/direction

echo 1 > /sys/class/gpio/gpio18/value

and the pin34--BT-RST-N ,come from low to high(3.3v)

then , I run this:

sudo ./brcm_patchram_plus -d --enable_hci --no2bytes --tosleep 200000 --use_baudrate_for_download --baudrate 115200 --bd_addr "11:22:33:44:55:66" --patchram /lib/firmware/bcm/AP6236/BT/BCM4343B0.hcd /dev/ttymxc1 &

the console printf always as below:

writing

01 03 0c 00

......

01 03 0c 00

the same operate can success to update fireware on the other develop board,

please someone can tell me ? what maybe the problem ,, I am sure uart2 is OK....

is the timing of pin6--BT-WAKEUP ,or pin34--BT-RST wrong?
