Bring up the custom imx6 dual board

[letan]

Hello together,

This is the first time I bring up so may imx6 hardwares for my customer . My hardware has:

• MCIMX6D5EYM10AD imx6 dual; MT41K512M16HA-125 RAM; MTFC8GLCDM eMMC
• jtag connector
• uart 1

Below is my plan for bringing up:

1. Flash DDR3 calibrate binary through JTAG (don't have u-boot this time)
2. Run DDR3 binary and get the configs when calibrating DDR3
3. Fill DDR3 configs to u-boot source code
4. Porting u-boot to boot from eMMC

This is my questions related to the steps to bring up hardware:

1. Which UART do I need to get the configuration when calibrating DDR3 stress test (UART1? or UART0?)
2. Any driver for RAM MT41K512M16HA-125?
3. Do I need driver for MTFC8GLCDM eMMC when bringing up?

Thanks,

Tan

Hello,

  You may check memory using the DDR stress tool, which needs only

USB OTG port of the i.MX6 : the result is sent to PC through USB

and displays in the log window. Also, JTAG-loadable version is located
there. No UART is needed.

For memory initialization, please refer to the following :

i.Mx6DQSDL DDR3 Script Aid

As for eMMC support, please refer to the following :

i.MX6: Accessing boot/user partitions on eMMC

Customer Borqs(ChinaTSP) encounter some issues when implement “raw eMMC driver” in i.MX6 platform.

Have a great day,
Yuri

Hi Yuri,

Because my board don't have USB OTG port but UART 1 and JTAG connector. So could you please show me how to get the result when calibrating RAM?

I am looking forward to your help!!

Thanks,

Hi,
  the mentioned stress tool has JTAG and UART based release :

Our hardware doesn't have USB OTG port. How can I get the result when checking RAM?

I am looking forward your respond!!!

Thanks,
