Our new project now customer feedback an issue is that  usb device disconnect from computer sometimes but it can recover connect immediately. MCU module: MCIMX6U5EVM10AC Action: 1. USB eye diagram test is OK , 2. if USB device connected to computer then remove the usb cable , but measured the USB_OTG_VBUS still output 4.4V(all of the… (Show more)

Hello,           i want to work on imx8qm mek board. I am building android, Along with that I want to implement Xen on this. I would like to know how the booting process takes place when xen is being implemented along with it (i.e is the boot process architecture). Is it possible to boot android on domain 0 instead of linux. Thanking you

我看在AN2165中有个描述写的是在MPC8260A中“the MPC8260A (HiP4) and revision C of the MPC8260 can use these values but require an external multiplexer.”是否MPC8280CVVQLDA型号也是如此?

Hello, Community.   Previously, when I asked about how to recover from an abnormal image written on the MCIMX7SABRE board, I was advised to boot from an SD card or use a UUU. Thank you for your suggestion! I am checking it now.   By the way, I have a question. I think that QSPI flash can be erased and rewritten if it is set to something other… (Show more)

Hello Team  Could anyone tell me is there a working driver for tlv320aic3104 under linux version 4.14 , based on imx8m? To make tlv320aic3104 works, what driver's components at least that I should port in? I just found one codec driver named tlv320aic3x.c, where could I get the machine part ? And is there any thing else I should port and… (Show more)

Hello !   I have combine gint and power management example from SDK ( code in attachment also ) and find out that I need to reinitialize GPIO pins what are included in PINT almost completely.   1. I have included SW2 and SW3 pins(buttons) to GINT0/1 and PINT ( 0,1 interrupt slot). When MCU switching between ACTIVE and SLEEP modes, it is no… (Show more)

Hi !   I have got the next limitation what I not understand quite well.   By using PINT peripherals I'm able to have only 8 individual pins what can generate individual type of interrupts, edges /levels and etc. ( patterns can be used instead of individual pins.)   And looks like PINT interrupts is not able to wakeup  Core0 from Sleep mode.… (Show more)

This tutorial is introducing the eRPC (embedded remote procedure call) open-source project.   The eRPC (Embedded Remote Procedure Call) is a Remote Procedure Call (RPC) system created by NXP. An RPC is a mechanism used to invoke a software routine on a remote system using a simple local function call. The remote system may be any CPU connected by…

Hello! The i.MX 6ULL hardware development guide recommends using the footprint designed by NXP. It also states that the native allegro gerber files are available on nxp.com. I can't find these files. I can get the 14x14mm package footprint from the EVK gerbers, but can anyone point me to the 9x9 mm package footprint?   I can just create it based… (Show more)
