Debug Connection

The TQMa8Mx debug UART is connected via a Silicon Labs USB-to-Serial converter to X16 (micro-USB) on the MBa8Mx. A micro-USB/USB-A cable is part of the STKa8Mx accessory set. Depending on the host operating system, a driver may need to be installed.

Yocto Deployment

Device assignment

Device assignment:
mmcdev 0 = eMMC
mmcdev 1 = SD Card

Yocto specific command Update eMMC

1. Run the following commands in the Uboot shell to create update script: 

 
setenv root_loop 'setenv start 24000 && setenv r1 $rootblks16 && while itest $r1 -gt 0; do if itest $r1 -gt 0x100000; then setenv count 0x100000; else setenv count $r1; fi && mmc dev 1 && mmc read $loadaddr $start $count && mmc dev 0 && mmc write $loadaddr $start $count && setexpr start $start + $count && setexpr r1 $r1 - $count; done; setenv r1; setenv start; setenv count'
 
setenv  install_firmware 'echo MBR... && mmc dev 1 && mmc read $loadaddr 0 1 && mmc dev 0 && mmc write $loadaddr 0 1 && echo Bootstream... && mmc dev 1 && mmc read $loadaddr 41 1FBE && mmc dev 0 && mmc write $loadaddr 41 1FBE && echo U-Boot environment... && mmc dev 1 && mmc read $loadaddr 2000 2000 && mmc dev 0 && mmc write $loadaddr 2000 2000 && echo Firmware Partition... && mmc dev 1 && mmc read $loadaddr 4000 20000 && mmc dev 0 && mmc write $loadaddr 4000 20000  && echo Root FS... && run root_loop'
  • Create the variable rootblks16 to hold the size of the root filesystem as a hex number representing the size as the amount of 512 byte blocks:
setenv rootblks16 <number of 512 byte blocks as hex number>
Example for RootFS size of 2070MB:
2070 * 1024 * 1024 = 2170552320
2170552320 / 512 = 4239360
4239360 = 40B000HEX
setenv rootblks16 0x40B000

uboot command to start netboot

=> run netboot
