STM32H747 with TW2835

[관박.1]

systme is TW2835 with stm32h747

i catch video data but

DCMI->DR cannot write to sdram buffer with DCMI DMA

this is DCMI, DMA Sorce

 hdcmi.Instance = DCMI;

 hdcmi.Init.SynchroMode = DCMI_SYNCHRO_HARDWARE;

 hdcmi.Init.PCKPolarity = DCMI_PCKPOLARITY_RISING;

 hdcmi.Init.JPEGMode = DCMI_JPEG_DISABLE;

 hdcmi.Init.ByteSelectMode = DCMI_BSM_ALL;

 hdcmi.Init.ByteSelectStart = DCMI_OEBS_ODD;

 hdcmi.Init.LineSelectMode = DCMI_LSM_ALL;

 hdcmi.Init.LineSelectStart = DCMI_OELS_ODD;
