AM2732: How many EDMA parameter sets are in AM2732?

Chris Meng

Part Number: AM2732

Hi，

In AM2732 TRM, some info shows there are 128 EDMA parameter sets, but some shows 512.

And in mcu plus sdk, it defines number of parameter sets to 256.

mcu_plus_sdk_am273x_08_02_00_26\source\drivers\hw_include\am273x\cslr_soc_defines.h
/** @brief Number of PaRAM Sets available */
#define SOC_EDMA_NUM_PARAMSETS             (256U)

Would you pls kindly advise which info is correct?

Thanks,

Chris

Hi Chris Meng

This issue has already been reported to the internal team and we have a JIRA ticket on this. [SITARAAPPS-1918] AM273x TRM - EDMA chapter missing & incorrect information - Texas Instruments JIRA

The correct number of sets is 128.

Kowshik,

Thanks for your help!

Would you pls also inform SDK team to correct the setting in SDK software? Same issue in latest sdk. mcu_plus_sdk_am273x_08_03_00_18\source\drivers\hw_include\am273x\cslr_soc_defines.h

/** @brief Number of PaRAM Sets available */
#define SOC_EDMA_NUM_PARAMSETS (256U)

Best Regards,

Chris
