fast boot with eMMC boot mode in i.MX8

双朋赵 — Thu, 14 Nov 2019 01:47:15 GMT

Hi everyone,

i.MX8x use SCU early boot+M4 freeRtos/Autosar to achieve 100MS CAN message answer time from power on when boot with eMMC(not nor flash).we have test the latest released MCU BSP(SDK_2.5.2_MEK-MIMX8QXP), the time from boot up (eMMC boot mode) to can answer time is about 250ms, it can not meet our customer's requirement, so we hope to optimize the bring up time and need your help.

Thanks.

Hi Shuangpeng

this processor is not publicly released yet and unfortunately has not full support,

for further help suggest to proceed with extended support of Commercial Support and Engineering Services | NXP
