LPDDR initial check for custom board

Robbi — Thu, 02 Jan 2025 05:48:38 GMT

Hi Team,

we had designed a custom-board with imx-93 processor. As a part of board bring-up activity. Need to test LPDDR4 ,eMMC and other peripherals. Is there any approach to test in u-boot stage with flashing image.

Thanks,,

Robbi.

Hi,

Thank you for your interest in NXP Semiconductor products,

For testing DDR, you would need to use Config Tools for the i.MX 93, you have to port your timings and characteristics into a new imx-boot image, the bring up is done through this interface and the test would be to get to U-boot after each boot.

For other interfaces like eMMC and so on, upon successfully porting your new imx-boot image with a custom u-boot, you could test your own code in the board.c file and/or through the U-boot commands, e.g. mmc read/ mmc write.

Regards

Thanks @JosephAtNXP , Is there any sample application to test eMMC and QSPI NOR FLASH memory(instead of using mmc or dd commands).
