Hi,
This is about the same product as my previous post: https://renesasrulz.com/rz/rz-a-azure-rtos/f/forum/18944/usb-mass-storage-host-with-dma-support-on-azure-rtos-needed
We want to add a SDHI host to the same hardware.
We've already ported some Renesas SDHI driver to our board. This works, but given how this was just a quick & dirty port to test the hardware, the result is not pretty or maintainable. We would prefer if Renesas added first class support to the rza1_gcc_azure_rtos_bsp repository. This way we can be sure of broad compatibility and benefit from future bug fixes to the SDHI driver Like with USB, DMA support is very important.
Does Renesas have plans to add such a driver to rza1_gcc_azure_rtos_bsp?
Renesas have no plans to add the SD controller DMA support to rza1_gcc_azure_rtos_bsp.We apologize for any inconvenience.But Renesas is preparing the SD driver(support DMA) for Non-OS.If you need it, please ask Renesas sales persons.
