TMDSEVM572X: Design queries

Part Number: TMDSEVM572X
Other Parts Discussed in Thread: AM5728

Hi TI Support,

1. TPS22965DSG has slew rate control with 220pF capacitor in evaluation board while our custom design will have 3100mA on 3.3V through this IC, so do you any slew rate change is required for any power sequencing, etc or 220pF should be fine.

2. We want to interface 16Gb NAND Flash MT29F16G16ADACAH4-IT as 2GByte X 16 on GPMC, are there any Linux drivers available for that?

3. eMMC NAND flash used in evaluation board is MTFC4GACAJCN-1M WT which is -25'C to +85'C, can we replace directly with -40'C to +85'C P/N: MTFC4GACAJCN-4M IT of any driver changes will be required?

4. How can we implement USB OTG configuration in AM5728, Mux utility tool doesn't shows separate USB_ID pin.?

Thanks,

jagdish

Hi,

1. Load switches are supported on a different forum: e2e.ti.com/.../949 Please ask there.
2. This is a direct replacement, no hardware or software changes are needed.
3. Full OTG is not supported. See processors.wiki.ti.com/.../Linux_Core_DWC3_User's_Guide. See also processors.wiki.ti.com/.../AM57xx_Schematic_Checklist On AM57x devices there is no dedicated USB_ID pin. A GPIO input is used, which must be grounded for Host mode, and pulled up for Device mode.

I missed this. Yes, there is NAND support in the Linux SDK. See processors.wiki.ti.com/.../Linux_Core_NAND_User's_Guide

Hi Biser,

Thanks again for the confirmation. BTW, can you pls put reminder to Ahmed since I am unable to get any response from him pertaining to thermal & power management queries.

Hi Biser,

Please note I would like to remind, I posted load switch query in pertaining forum but that was moved again to Sitara forum & still there is no response. Can you please look into this. Link below for your reference.
