Part Number: AM625

Tool/software:

Hi expert,

Our customer is trying config McASP as burst mode, and then they can get clokc, fs, data signal. But when they try to config txstafrm, they cannot get interrupt response.

The interrupt is enabled as below:

The interrupt is enabled. They can get clock signal but clock failure bit is set.

Hi Xingyu,

What version of SDK are you using to test this? Is it a custom board or actual AM625 EVM that you are verifying the burst mode

Hi Xingyu,

Can you refer the section 12.1.1.4.9.1 Burst Transfer Mode in the TRM where it clearly states what configurations are required in order to have burst mode enabled.

Also can you ask the customer to check the MCASP_RINTCTL/MCASP_XINTCTL: Program all fields according to interrupts desired as mentioned.

Best Regards,

Suren
