Hi,
There are some problems in EDMA3_DRV_requestChannel(),
the err return is EDMA3_DRV_E_DMA_CHANNEL_UNAVAIL (/** The requested DMA Channel not available */)
As the result of EDMA3_DRV_requestChannel() err, err log at vision_sdk/links_fw/src/rtos/utils_common/src/file_api_dma (v3.4) is[IPU1-0] 67.171475 s: Assertion @ Line: 101 in file_api_dma.c: edma3Result==EDMA3_DRV_SOK : failed !!!
For more details, the err point is at EDMA3_RM_allocResource() in ti_components/drivers/edma3_lld_02_12_00_20/packages/ti/sdo/edma3/rm/src/edma3resmgr.c
if dma ch is 47,
rmInstance->initParam.rmInstInitConfig->ownDmaChannels[resId/32U] = 0xffff_0000
resIdSet = 0x0000_8000
(rmInstance->initParam.rmInstInitConfig->ownDmaChannels[resId/32U]) & resIdSet = 0 ==> it returns err of EDMA3_RM_E_RES_NOT_OWNED

P.S.
It's for eMMC driver, MMC2_INST is used instead of MMC1_INST (SD), and EDMA channels of 46 (TX) and 47 (RX) are used for it.
eMMC booting is working after some modification of SBL code as your reference,
