sd1 using SDK 2.10.1 dev_msc_disk_bm_SDIO

[iblades_dan]

Hello everyone,

I'm trying to bring up the dev_msc_disk_bm_SDIO example on my customer hardware with two SDMMC devices (MCU is LPC55S69 with one SDMMC device connected to SD0 and one SDMMC device connected to SD1).

If I use SD0 (g_sd.hostPort = 0), the card initializes properly, it enumerates to a PC and the PC can read/write SD0.

If I try the same for SD1 (g_sd.hostPort = 1), SD1 does not initialize successfully.  Instead the example code times out waiting for a kSD_Inserted event, even though there's a card in SD1.

Anyone have any insight into this issue?

Thanks,

DanL

Hi Alice, thanks for your quick reply!  Attached is a screenshot of the example I've imported.

Can you clarify what you mean by "other configuration?"

Best,

DanL

Hi Alice, a quick update - I got SD1 working properly this evening.

Support for SD1 was only partially implemented in the example driver, an area I'd like to see NXP do better.

Implementing a driver function in "bits and pieces" often makes it harder to identify what's needed.

Regards,

DanL

Hello iblades_dan,

How about other configuration?

And does the demo " dev_msc_disk_bm_SDIO "  under SDK? Is it the whole name? I haven't find this demo.
