Insufficient RAM for Flash Algorithms !

I clone the repository on GitHub, which is the accompanying code for the Application Note nAN-36 "Creating Bluetooth Low Energy Applications Using nRF51822", in the nrf51822/Board/pca10001/s110/ folder. Though I can successfully build the project, I can not download the image the the PCA10001 target board. The log is as shown below:

Insufficient RAM for Flash Algorithms ! Erase Failed! Error: Flash Download failed - "Cortex-M0"

"Insufficient RAM for Flash Algorithms ! ?" what is that mean? How did it happen?

I did download the S110 SoftDevice using nRFgo Studio before downloading the application image within Keil μVision.

Thank you for your help.

  • Thank you for your reply and support. The following are the original settings from Project -> Options for Target 'nrf51822_xxaa_s110 (256K)'

    The following are the new settings based on your suggestions and some clues from your Bluetooth low energy heart rate monitor demo.

    ​I can build the project without any error and download to the PCA10001 board successfully. But, when I click "Start Discovery" within the "Master Control Panel", the nRF51822 Development Dongle can not scan any available Bluetooth low energy devices within range. There might have some other settings needed to be adjusted to make the demo work. Thank you for your answer.

  • Hi all, I had same problem resolved with these tips. However, as Tsan-Ming said, once downloaded the code into PCA10001 v2.2, the dongle (PCA10000) previously loaded with SoftDevice 7.1 don't discover any BLE device. Tsan-Ming, have you ever solved this issue? Thank you!
