SK-AM62-LP: Looking for following peripheral drivers from MCU-PLUS-SDK-AM62X — MCU+ SDK for AM62x – RTOS, No-RTOS

also, is ADC under EPWM module?

The query has been assigned to the expert. Please expect a response within a day or two.

Thanks!

dma: that can transfer from one memory location to another memory location

The answers below are based on the MCU+SDK and not based on the Linux side.

The example below is used to transfer data from DDR to DDR with DMA.

crc: crc calculation

Which CRC calculation you are talking about?

Can you please elaborate why CRC calculation is needed and where you want to use it ?

The AM62X device does not have any internal ADC and RTC Modules.

But, the App note below is helpful for how to interface ADC and RTC modules externally.

Hi Swargam,

It is the cyclic redundancy check (CRC). This is used to calculate some data in a NAND flash. Sometimes we will need to verify the data is still valid after a cold reset, and CRC is one of the checks we will use.

timer/lptimer: count up, count down, interrupt

Hello  Dazong,

Currently in MCU+SDk, we do support overflow Timer interrupt.

You can simply configure Timer from MCU+SDK and generate code.

I assume that you are expecting some data validation after reading data from NAND devices.

The AM62P devices support a GPMC ELM module which detects errors in the data read and corrects them with the help of the BCH method.

This is already supported in the MCU+SDK.

If you need more details on this topic please go through the chapter below.

Thanks Anil,

It doesn't necessary needs to be nand, but CRC gives a more flexible way to validate if the data is correct. Is CRC available or not? Or we need to make our own?

Thanks,

Dazong

Hello Dazong,

The GPMC module does not support CRC validation and users need to implement their own CRC validation if they need it.

Anil.

Thanks for clarification Anil,

What about OTP write/read?

Hello Dazong ,

Please check for OTP examples from the path below.
