CCS/CC2652R: CC2652R SRAM

user5357018

Part Number: CC2652R

Tool/software: Code Composer Studio

Hello, CC2652R has 80KB of Ultra-Low Leakage SRAM and Ultra-Low Power Sensor Controller With 4KB of SRAM, I define three tasks ,which include uint8_t EM1068appTaskStack[2048] ,uint8_t DisplayappTaskStack[2048] ,uint8_t AFE4900appTaskStack[2048] and uint16_t rectflushBuff[22*240],total 16K. When I build this project.It occurs error as follows:

<Linking>

Hello,

0x11f17 is greater than 0x11bd8, so you are off by 831 bytes. Maybe there is something else in your code that is consuming more RAM. So please do the following:

1. Change your rectflushBuff to rectflushBuff[[18*240]. This change should allow you to build your project

2. Open the memory allocation View > Memory Allocation and expand SRAM as the image below.

Hopefully this will give us more information on where the RAM leakage is?

Best regards,

David

Hello, I run the project of project_zero_cc26x2r1lp_app in simplelink_cc26x2_sdk_2_20_00_36 , the program sometimes crashes. The position locates

Hello,

You may want to take a look at the debugging section in the ble stack users guide.

dev.ti.com/.../debugging-index.html

Especially the ICall Abort subsection:
