iMX6Solo Flash Empty eMMC

zemanel1991 — Thu, 22 Dec 2016 14:04:31 GMT

Hi.

I'll have my own board with an iMX6Solo and I need to know the possible ways to flash it (the board comes from production). I "want" a process to flash the boot loader without using an USB Pen or an SD card (as documented on most development boards).

How does the process works using the MFGTool and what version should I use?

Is there any other process?

eFuses are programmed during this process or after I have the boot loader running?

Hi Ze

for programming emmc recommended to use mfg tools (each kernel release has own version),

please check below link and folder /Document in package

Hi.

Thanks for the answer.

Can I do the same using JTAG? How this process is done? I'm thinking not including USB OTG.

You can program it via U-Boot like we do on warp7:

I see... But I really need to know how I can do it using JTAG.

Hi Ze

uboot answer meant that uboot could be run with jtag.

Hi.

Thanks again.

I'm trying to program via U-boot as you suggested but when I run the command $ sudo dfu-util -D u-boot.imx -a boot (Transfer u-boot.imx that will be flashed into the eMMC:), I get:

dfu-util: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!
dfu-util: No DFU capable USB device available

Any idea?

Best regards.

Make sure you have added DFU suppor to your board. Take a look at include/configs/warp7.h and board/warp7/warp7.c as reference on how to do that.

Hi.

I'm using JTAG (openocd + gdb/telnet) to load u-boot into RAM (similar to using USB and Serial Download mode). However, I'm having problems similar to those described in other threads.
Have you got any example to do that?

I've followed the post imx6, arm, and linux - tips and tricks: Inexpensive JTAG on the imx6 solo: U-Boot Launch and Debug, but I'm facing problems like:

> load_image u-boot.bin
JTAG-DP STICKY ERROR
MEM_AP_CSW 0x42800062, MEM_AP_TAR 0x0
Failed to write memory at 0x00000000

If I force an address, I can load the image but the board doesn't boot, and, automatically, it jumps to serial download mode...

Any suggestion?

Best regards
