i.MX6 Ultralite Mass Production Question

[nachodiz]

Dear all!

We want to start mass production of our boards after passing all the testings sucesfully (2k-50k year)

I´m not able to find fuse blowing and emmc flashing houses to have emmc and MPU ready at Pick And Place Lines

Should i use MFG tool, i think its too slow?

Alsho this forces me to place the Boot CFG Dual DIP SWITCH that is expensive

King Regards

For mass programming you could use a test fixture with pogo pins, using this pins you could force a boot for example form an SD card placed in the test fixture.

This SD card would boot and program your board.

Another solution is to use JTAG to flash the eMMC and blow the fuses. You can contact for example Segger and probably they can adapt their software in order to support your application. Also they have standalone JTAG programmers.

Hello,

 Please look at the following :
 
1.
https://community.nxp.com/docs/DOC-95458 
 
2.

 For MFG, in script file ucl2.xml, you can see / add  commands to write OTP (as an example) :
 
    <CMD state="Updater" type="push" body="$ ls -la /sys/fsl_otp ">Showing HW_OCOTP fuse bank</CMD>
    <CMD state="Updater" type="push" body="$ echo 0x00006200 > /sys/fsl_otp/HW_OCOTP_GP1"
             write 0x00006200 to HW_OCOTP_GP1 fuse bank
   </CMD>
    <CMD state="Updater" type="push" body="$ cat /sys/fsl_otp/HW_OCOTP_GP1">Read value from HW_OCOTP_GP1 fuse bank

    </CMD>

Regards,

Yuri.
