Hello,
I'm working on a new design based on the Cortex-M4 LPC4337 (NXP) On my board, there is a e-MMC Memory (MTFC4GMDEA-1M WT) with 8-bit data interface. My µVision version is 4.74 and I'm using the driver SDIO_LPC43xx.c. I'm selecting the Memory Card Drive 0 with the SD-Native Bus Mode. But the finit() function is always failing.
Any suggestions? is the 8-bit interface the problem ?
regards, Jean-Marc
Wouldn't Keil support be a better channel for your question?
See the top or bottom of every web page.
Update on this issue: There is no eMMC support in our middleware for MDK 4.x. However, you can update to MDK version 5.12 or later and either install the corresponding legacy pack or convert/setup your project based on a device family pack (DFP).
