Hmm.

I never played with SGDMA up to now, and did not yet look into the sources, but two instructions toggling one or more bits should look more like this:

rx_sgdma->control &= ALT_SGDMA_CONTROL_SOFTWARERESET_MSK;

rx_sgdma->control |= ~ALT_SGDMA_CONTROL_SOFTWARERESET_MSK;

Moreover rx_sgdma needs to be defined volatile to make it work.
