LPDDR2 support on imx6sll

buy — Fri, 07 Jun 2019 08:57:03 GMT

Hi,

The iMX6SLL Data Sheet (https://www.nxp.com/docs/en/data-sheet/IMX6SLLCEC.pdf) clearly states, that iMX6SLL supports BOTH LPDDR2 and LPDDR3. We have bought a huge branch of iMX6SLL (MCIMX6V7DVN10AB) to use in our Yocto project.

However, now I cannot find the full support of LPDDR2 in BSP. In particular, for the deep sleep.

Could somebody clarify the situation?

Thanks

Hi dR

seems one can reuse i.MX6SL EVK software (lpddr2 based design) as

i.MX6SLL is pin-to-pin compatible with i.MX6SL, according to AN11988

"i.MX6SLL Migration Guide, Migrating from i.MX6SL to i.MX6SLL "

https://www.nxp.com/docs/en/application-note/AN11988.pdf

also one can look on linux/arch/arm/boot/dts/imx6sll-lpddr2-arm2.dts

imx6sll-lpddr2-arm2.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel

linux/arch/arm/mach-imx/suspend-imx6.S

suspend-imx6.S\mach-imx\arm\arch - linux-imx - i.MX Linux kernel

Linux documentation (Linux Manual, "Low Level Power Management (PM)")

i.MX Software | NXP

Best regards
