SD110- 7.1.0

BLE
Fixed an issue, effecting nRF51 chips with more than 16 kB of RAM, that could cause an assert at  or cause sd_ble_enable()
SVC calls to return NRF_ERROR_INVALID_ADDRESS when a pointer to RAM above 16 kB was supplied (DRGN-4927,
NRFFOETT-900).
Fixed an issue where sending data after the link had been disconnected might lead to reduced maximum throughput for the next

connection (DRGN-4519)

I missed to see that you are using SD6.0, i am not sure if you can use 32k with that old SD

compile your program with this keil settings Target_options->C/C++->optiomizations->Level 0

flash the code and set the breakpoint at the line next to where "err_code = sd_ble_gap_dev_name_set is called. run the debugger. And when the breakpoint hits, you can check what the err_code is.

The program is stop at sd_ble_gap_device_name_set,i can not find what error,can you tell me how can to find the error?

IROM1 =0X1400 does not look right. shouldn't this be IROM1 =0X14000 Also what error do you get?

OK. 1, I used S110 V6.00,IROM1 =0X1400 SIZE=0X28000,IRAM1=0X20002000 SIZE =0X6000 2.I select the chip is nrf51822QFAC 3.I download the program to nrf51822 QFAC if the ram used size less than 0x2000,then the nrf51822QFAC work is OK. 4.I download the program to nrf51822 QFAC if the ram used size more than 0x2000,then the nrf51822QFAC work is wrogn. 5.I find the error at err_code = sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)DEVICE_NAME, strlen(DEVICE_NAME)) function.

I am not sure if I understood your question correctly. If you have problems running your code with 32k RAM and if the code was working with 16k RAM, check if you have selected the correct chip in your target settings and also check if you IRAM values match as in here
