MSP430FR6007: DMA usage in 20Bit address room fails

Part Number: MSP430FR6007

Hi There,

I hat this topic, unfortunately it was closed: MSP430FR6007: crc_table function - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums 

I boiled it now down to the 20 bit address room, my dma feeder works when Im 64kb address room in relation with the CRC module,

Unfortunately when I get in to extended address room 0x10000 it kills the system:

Basic question: Does the MSP430FR6007 DMA module support the extended address room?

    DMA_initParam cfg = {
        DMA_CHANNEL_0,                 // channelSelect
        DMA_TRANSFER_BLOCK,            // transferModeSelect
        static_cast<uint16_t>(length), // transferSize
        DMA_TRIGGERSOURCE_0,           // triggerSourceSelect
        DMA_SIZE_SRCBYTE_DSTBYTE,      // transferUnitSelect
        DMA_TRIGGER_RISINGEDGE         // triggerTypeSelect
    };

    DMA_init(&cfg);

    // Use proper 20-bit address handling
    // Convert pointers to 32-bit first to avoid truncation
    uint32_t volatile src_addr = reinterpret_cast<uint32_t>(src);
    uint32_t volatile dst_addr = reinterpret_cast<uint32_t>(dst);

    // Set the Source Address (20-bit)
    __data20_write_long((uint32_t)&DMA0SA, src_addr & 0xFFFFF);

    // Reset bits before setting them
    HWREG16(DMA_BASE + DMA_CHANNEL_0 + OFS_DMA0CTL) &= ~(DMASRCINCR_3);
    HWREG16(DMA_BASE + DMA_CHANNEL_0 + OFS_DMA0CTL) |= DMA_DIRECTION_INCREMENT;

    // Set the Destination Address (20-bit)
    __data20_write_long((uint32_t)&DMA0DA, dst_addr & 0xFFFFF);

    HWREG16(DMA_BASE + DMA_CHANNEL_0 + OFS_DMA0CTL) &= ~(DMADSTINCR_3);
    HWREG16(DMA_BASE + DMA_CHANNEL_0 + OFS_DMA0CTL) |= (DMA_DIRECTION_UNCHANGED << 2);

    // Clear DMA interrupt flag and start transfer
    DMA0CTL &= ~DMAIFG;
    DMA_enableTransfers(DMA_CHANNEL_0);
    DMA_startTransfer(DMA_CHANNEL_0);

    // Poll for completion
    while (!(DMA0CTL & DMAIFG))
    {
      __no_operation();
    }

    DMA_disableTransfers(DMA_CHANNEL_0);
