Tool/software:
Dear TI Team,
I currently have a TI LaunchPad kit featuring the Sitara AM263x MCU. I would like to know if it is compatible with the DRV8316REVM.
Thank you for your assistance.
Best regards,
Hello Shahar,
I don't believe we've reviewed this EVM for compatibility before, it would come down to the pinout. I'll have one of our motor control experts review this.
Best Regards,
Ralph Jacobi
Hi Ralph,
Thank you for your response.
I am interested in working with the Sitara AM263x MCU and the DRV8316REVM motor driver. What options are available to achieve this? Additionally, are there any example projects, even for similar motor drivers, that I could refer to?
I appreciate your support and look forward to your guidance.
Hello Shahar,
The current LP-AM263x version (Rev. E2) isn't fully compatible with the DRV8316REVM because of one pin limitations for the SPI connection on the LP-AM263. However, the next version (Rev. A) will work with this EVM. In the meantime, you can check out the TIDM-02018 design guide to help you add support for the DRV8316REVM for Rev. A.
Best,
Masoud.
Hi Masoud,
Is there a way to bypass the pin limitation in the current version? To clarify, is it completely impossible to use the LP-AM263x with the DRV8316REVM, even if I manually connect the pins wire by wire? If it is possible, could you guide me on how to set up the wiring and what changes need to be made in the AM263_3phGaN_3SC.syscfg file?
Also, when is the next version expected to be released?
Additionally, could you recommend a similar product to the DRV8316 that would be compatible with the LP-AM263x? We are running a BLDC motor at low RPM, approximately 0.15.
Thank you,
Shahar
Hey Shahar,
Last time I looked into it, there’s a pin linked to selecting a mux for the SPI pins on the Launch Pad. When we were picking SPI, there were some limits on getting ADCs to the pinouts. I believe the DRV8316REVM will be ready for the next version of the LP.
As for the Rev A LP-AM263 release, I’ll loop in Ralph to tackle that question.
For the AM-263, the best project to kick things off with is TIDM-02018, which also has the migration guide.
Best,
Masoud.
Dear Masoud,
If I were to use the DRV8316REVM with a different board, what are the essential pins that need to be connected to activate it?
Secondly, is the issue with this LaunchPad version that the ADC and SPI pins are shared, creating a limitation? . there is no option to configure other pins to SPI/ADC?
Lastly, does the BOOSTXL-3PHGANINV from TIDM-02018 support FOC or sinusoidal 180° control? My motor is sinusoidal with an EQEP encoder, and I would like it to operate at low RPM.
Thank you!
Shahar
Shahar,
I chatted with the team, and the new version of LP-AM263 Rev. A should be ready to order on ti.com by the end of Q1.
You'll have to hold off for Rev A since the current board setup can't support both SPI and ADC at the same time.
Plus, TIDM-2018 supports FOC control because it has better dynamic performance.

Hi Masoud,
Thank you for your response.
Regarding the Universal Motor Lab software, does it use SPI only during the initial configuration of the DRV? If that's the case, would it be possible to configure the DRV first and then switch to ADC for operation?
I appreciate your insights!
Best regards,
Shahar
The universal lab for AM-263 (TIDM-02018) currently doesn't have support for the SPI-based driver. We're planning to add support for the DRV8323RS first.

Hi Masoud,
The DRV8316 has a non-SPI mode that allows hardware pin-based configuration. If I use this option, is there a way to interface it with the Sitara?
The Sitara supports SPI and ADC—can you please explain the problem? Maybe we can adjust the pin setup to make it work.
yes, you can move forward with no-SPI variant of AM-263 with no issue. You can follow the instruction to migrate to different board in TIDM-02018 design guide.
Best Regards,
Masoud
Hi Masoud,
Thank you for your response.
Are there any specific peripherals (e.g., MSPI, I2C, etc.) that I need to disable when migrating to the no-SPI variant of the AM263?
No, you don't need to disable any peripheral by default.
Best Regards,
Masoud
