CCS/CC2640: CCS download problem

Do you download BEL Stack example? If so, which BLE Stack version and example do you use?

yes I import the SimpleBLEPeripheral project and SimpleBLEPeripheralStack project from the CCS ->project->example. I have import TI-RTOS for SimpleLink Wireless MCUs 2.13.0.06

I suggest you to download/install latest BLE Stack v2.2.1 and use CCS7 to build simple_peripheral example in BLE Stack v2.2.1

thank you I will have a try

You are welcome.

hello,when I change the "CC2650_LAUNCHXL" to "CC2650DK_4XS" of predifine symbles in CCS7,there are some errors when building the project simple_peripheral_cc2650lp_app,Such as ""C:/ti/tirtos_cc13xx_cc26xx_2_20_01_08/products/tidrivers_cc13xx_cc26xx_2_20_01_10/packages/ti/mw/extflash/ExtFlash.c", line 113: error #20: identifier "Board_SPI_FLASH_CS" is undefined
"?

I suggest you to use simple_peripheral example in ble_sdk_2_02_01_18\examples\cc2650em to do this test instead of simple_peripheral for LAUNCHXL-CC2650.

Do you try to use TI SimpleLink Starter APP on iPhone to see if it can scan your CC2640F128RSM?

TI SimpleLink Starter APP can't scan my board at all

When you build simple_peripheral example in CCS, do you use TI ARM Compiler version 5.2.6?

dosen't work

Do you use TI ARM Compiler v5.2.6?

yes

I test this with my CC2650_4XS and it works fine. I suggest you to check your HW first.

when i download the pwm project for CC2650_4XS in ccs examples cloud, it works as well.

Try to download attached hex files to your CC2640_4XS to see if it works.  Those hex files works on my CC2640_4XS.

thank you, I download simple_peripheral_cc2650em_app project into CC2640F128. My iphone can scan my board. When i cennect iphone with my board,it failed with tips "Timeout interrogating the pergheral"

Check if your crystal is inaccurate.

The crystal on my board is 24MHz,need i to set it?
