aducm355 SRAM settings issue

sahilsawant on Jan 3, 2022

I have bought EVAL-ADuCM355 evaluation board recently. I have downloaded the keil uVision 5.36 and the examples provided on git repository. I want to try chronoamperometry example M355_ECSns_CapaTest. But I am getting some compiler linker error as below.

Error - .\Objects\M355_ECSns_CapaTest\M355_ECSns_CapaTest.axf: error: L6047U: The size of this image (59232 bytes) exceeds the maximum allowed for this version of the linker

The code has some guideline regarding RAM size as - uint32_t AppBuff[n][APPBUFF_SIZE] __attribute__((section(".ARM.__at_0x20040000"))); // use up to 32K bytes max, compiler linker file must have been modified for this to work !! Use "USER_SRAM_MODE = 2" setting;

I did not understand those meanings. I am using MDK-lite version.
Kindly find the attached images for reference.

Hi,

Have you done some modifications in the code? Because it shows size as way more than expected.

I have not changed the code. It is downloaded from github.

This time I have changed the compiler version but still got the same output (written below). Did you check using MDK-lite version (32KB size free version)

Output-

Hello,

I got the Trial license version from the ARM Keil team for 30 days. Code gets compiled and downloaded successfully. Could you tell me how to increase time duration in the chronoamperometry code?

Hi,

Do you mean reduce the output data rate?

pAMPCfg->AmpODR = 1;

Hi,

Yau can change

pAMPCfg->pulseLength = 100; /* Length of voltage pulse in ms */

in AD5940Main.c file
