GPIO export using User space

Dear team,
I’m Trying access GPIO pins of SC200E from user space.But i’m not able to access gpio_pin.

bengal:/ # cat /sys/class/gpio/gpiochip1153/base 1153
To export gpio100, I’m requesting 1153 +100. i.e : echo 1253 /sys/class/gpio/export.
but still I’m not able to access it.
dmseg logs are as following:

bengal:/ # dmesg | grep -i gpio [ 3.563449] bt_power_populate_dt_pinfo: bt-reset-gpio not provided in devicetree [ 3.570962] bt_power_populate_dt_pinfo: wl-reset-gpio not provided in devicetree [ 4.035300] genirq: irq_chip msmgpio did not update eff. affinity mask of irq 194 [ 4.931477] CAM_INFO: CAM-ACTUATOR: cam_actuator_parse_dt: 60 No GPIO found [ 4.938536] CAM_INFO: CAM-ACTUATOR: cam_actuator_parse_dt: 60 No GPIO found [ 5.925088] input: gpio-keys as /devices/platform/soc/soc:gpio_keys/input/input1 [ 5.962513] [FTS_TS/I]fts_parse_dt:max touch number:5, irq gpio:1233, reset gpio:1224 [ 26.990671] msm_cdc_pinctrl_get_gpiodata: device node is null [ 32.831537] is_ext_spk_gpio_support:Enter [ 32.866489] is_ext_spk_gpio_support:qcom,msm-spk-ext-pa gpio num 1211

Hi,
GPIO100 is used, you can’t export it.

Dear Great,

yes, there was wrong command “echo 1253 /sys/class/gpio/export”.
command should be : "echo 1253 > /sys/class/gpio/export
