Yes, the AM2612 SDK can support simultaneous SPI communication on two hardware modules with polling-based completion checking. Here&#39;s how to approach this: Parallel SPI Implementation Approach: Configure both SPI modules independently - Set up SPI0 and SPI1 (or your chosen modules) with identical timing parameters to handle 3 chip selects each (2 hardware CS + 1 software CS). Initiate transfers simultaneously - Use the SDK&#39;s non-blocking transfer APIs to start communication on both SPI modules back-to-back without waiting for completion: MCSPI_transfer(spi0Handle, &amp;spi0Transaction); MCSPI_transfer(spi1Handle, &amp;spi1Transaction); Poll for completion - Check the transfer status registers for both modules in a tight loop: while(!MCSPI_isTransferComplete(spi0Handle) || !MCSPI_isTransferComplete(spi1Handle)); Repeat for remaining chip selects - Execute this pattern three times (once per chip select group) to complete all 6 channel reads. Expected Timing: Single 6-byte transfer: ~5 &#181;s bus time + ~2 &#181;s overhead = 7 &#181;s Parallel 2-channel read: ~7 &#181;s per iteration &#215; 3 iterations = ~21 &#181;s total This should meet your 30 &#181;s requirement with margin Recommendations: Ensure both SPI modules are clocked from the same source for synchronization Use DMA if available to further reduce CPU overhead, though polling should be sufficient Verify CS timing meets your magnetic encoder specifications Please let me know which SDK version you&#39;re using and if you need additional assistance implementing parallel SPI configuration and polling mechanism.

Please give a try with the wic image, that I attached in my previous reply? We can get on a debug call, tomorrow if you are available in the afternoon. Best Regards Surenhttps://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1649414/am2612-q1-am2612-uart-automatic-rts-in-mcal/6361345Wed, 27 May 2026 20:34:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:ac49465a-34ed-4737-a5dc-eed9bcee987aFleenorHi Kita, Thank you for your question regarding RS-485 automatic RTS control on the AM2612-Q1. Hardware Capability Confirmed The AM2612 UART hardware does support RS-485 mode with automatic direction control. According to the AM261x Technical Reference Manual (SPRUJB6B), the RS-485 external transceiver direction control is implemented through the UART_MDR3 register. RS-485 Configuration To enable RS-485 mode with automatic RTS direction control, configure the following register bits: UART_MDR3 DIR_EN - Set to 0x1 to enable RS-485 External Transceiver Direction UART_MDR3 DIR_POL - Sets the polarity for the RTS/DIR signal: 0 = TX: RTS=0, RX: RTS=1 1 = TX: RTS=1, RX: RTS=0 The hardware automatically monitors the TX FIFO and TX shift register to control the direction signal. When both are empty, the transceiver is set to RX mode. There is a guard band delay counter of 3 bit clock cycles after the TX shift register empties to allow time for the stop bit to transition through the transceiver before switching to receive mode. MCAL Configuration Since there may not be a direct RS-485 GUI option in the current MCAL version, you will need to configure RS-485 mode through direct register access. This can be done in a post-initialization callback or user configuration hook after the standard UART initialization: /* Enable RS-485 mode with automatic direction control */ UARTx-&gt;MDR3 |= (1U MDR3 |= (1U &lt;&lt; 3U); /* DIR_POL - Set polarity (adjust based on your transceiver) */ Additional Verification Steps Confirm that the RTS/DIR pin is correctly assigned in your PINMUX/SysConfig settings Verify your MCAL version - newer releases may include explicit RS-485 configuration options Review section 13.1.4.4.8.2 &quot;RS-485 Mode&quot; in the AM261x TRM (SPRUJB6B) for complete details Check the MCU+ SDK for any RS-485 reference examples Reference Documentation AM261x Technical Reference Manual (SPRUJB6B), Section 13.1.4.4.8.2 UART_MDR3 Register details at offset 0x80h Please let me know if you need clarification on the register configuration or have additional questions about the implementation.

My notes were originally written in MD so if the formatting is a bit hard to read please paste the contents into an MD editor. I&#39;ll have another look through the SDK, the doc you pointed me to took me here: https://software-dl.ti.com/processor-sdk-linux/esd/AM62PX/11_01_05_03/exports/docs/linux/How_to_Guides/Target/How_to_boot_quickly.html#secondary-boot-loader-sbl I then followed onto here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM62PX/latest/exports/docs/api_guide_am62px/TOOLS_BOOT.html#LINUX_APPIMAGE_GEN_TOOL And I followed the Falcon boot instructions from there. I am missing something, so please if you can give me detailed instructions of how to do this that would be immensely helpful. Also, I have an SK-LCD1 display, any chance you could complete a build with that dbc override so I can replicate on my hardware? Thanks Tomhttps://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1649540/am6421-mcu-plus-sdk-cross-compatibility/6361302Wed, 27 May 2026 20:05:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:08a7b2b5-ff05-4dfa-8e26-4447bf592714Joe PaolinoHi Meet, As I re-read through the SysFW releases, we can definitely use the SA2UL timeout for DMA in Release 11, and the updated efuse timing parameters in 11.2. So with that I guess I could re-phrase the request for an 11.2 bootloader/SysFw and 10.1 Application. Are there any compatibility issues that would prevent that combo? Thank you, Joehttps://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1649579/mspm0g3507-q1-bsl-flash-through-uart-on-ccs/6361277Wed, 27 May 2026 19:41:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:0871bbcc-aa5a-40b6-9c54-2e33e7791ab2KiHello, [quote userid=&quot;527652&quot; url=&quot;~/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1649579/mspm0g3507-q1-bsl-flash-through-uart-on-ccs&quot;]Does the below config in CCS work to flash the MCU on LanuchPad through UART?[/quote] However the primary use of the &quot;UARTConnection&quot; is to enable GUI Composer access to target memory via UART.

Our target application is approximately 400 W, with 12 V / 24 V battery support and a 390–400 V HV DC bus. The design files we currently have from C2000Ware / controlSUITE include: SCH_{TXN010}_BiDirDCDC_rD.zip Inside that archive: SCH_BiDirDCDC_07_09_14_HN.sch A .asc file that appears to be a PADS PowerPCB ASCII netlist BOM in Excel Gerbers TI design guide / schematic PDFs, including tidrhs9 and tidrht0 The .sch file appears to be a PADS Logic binary schematic file from around 2014. Our hardware engineering team uses Altium Designer, but this binary .sch file does not import cleanly into Altium. The .asc file appears to be a netlist rather than a schematic ASCII export, so it also does not work as an editable schematic import source. Request: Is it possible to obtain the TIDM-BIDIR-400-12 schematic in any of the following alternative formats? PADS Logic ASCII schematic export Example: .txt file exported from PADS Logic using File → Export → ASCII Altium Designer project files Example: .PrjPcb / .SchDoc OrCAD Capture schematic Example: .dsn Even just the PADS Logic ASCII schematic export would be very helpful, since Altium can typically import that format more reliably than the binary PADS schematic file. We are not looking to redistribute the files. This is for internal engineering reference only, to review the TI power-board schematic and accurately map the controller and power-stage connections for our own board design. Could you please confirm the correct CAD tool/version used for the original schematic and whether TI can provide one of the alternative schematic formats above?

Can you try the following and see if it unlocks the device: 1. Disconnect the LaunchPad from power 2. Open a Uniflash session for the device (Check both device and debugger, or select the launchpad image) 3. Press and hold the NRST button (S3). 4. Connect the LaunchPad to power while continuing to hold the NRST button 5. Click on the &quot;Setting &amp; Utilities&quot; tab and click on/Issue a manual Factory Reset DSSM command 6.
