BLUENRG_LP STEVAL-IDV011V1 issue

[ARamí.1]

I can’t program my STEVAL using SWD neither UART right now.

My last FW only configures my accelerometer an them goes to SHUTDOWN.

When the MCU is on SHUTDOWN mode I could never program STEVAL using SWD (in Keil or using BlueNRG-X-Flasher Utility), but UART worked.

Error in Keil

Error in BluenRG-X-Flasher Utility

 

To reduce consumption I configured PA10 (BOOT pin) like ANALOG, FREQ_LOW, OPEN_DRAIN, PULL_NO. With default configuration the consumption goes up to 75uA on SHUTDOWN mode and with this configuration the consumption goes down to 150nA in my system. (I don’t use this GPIO in my FW).

I have other STEVAL with a FW with the same configuration in this pin and I can program STEVAL using UART. 

My question is if I’m doing something wrong or if there is a way to reset my STEVAL.

Thanks for your answer.

I solved the issue copying and pasting the binary image into the STIDB011V1 mass storage device.

Hold push button 1 and Reset button for some time then try to flash.

Hi @Adrian Ramírez Mengana​ ,

Solution given by @Nikhil Gayke​ is the right one.
