Known Issues Yocto

MBa57x

RS485

RS485 bus block in half-duplex mode
Affects RS485 via UARTx on MBa57xx Revsion 01xx
Issue During AM57xx reset the UARTx.CTS# pin is low by default (CPU internal pull down)
Effect Using the AM57xx RS485 circuitry in a half-duplex slave device or half-duplex multi-master environment may block the RS485 bus during AM57xx reset.
The bus is released as soon as the UARTx.CTS# pin is properly configured by software (e.g. U-Boot, Linux, etc.)
Solution / Workaround Add a 10k pull up to the UARTx.CTS# signal on carrier board
This behaviour will be fixed with MBa57xx REV.02xx

Yocto specific command Update eMMC

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

 
setenv root_loop 'setenv start 12001 && 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 0 && mmc read $loadaddr $start $count && mmc dev 1 && 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 0 && mmc read $loadaddr 0 1 && mmc dev 1 && mmc write $loadaddr 0 1 && echo U-Boot... && mmc dev 0 && mmc read $loadaddr 2 7FE && mmc dev 1 && mmc write $loadaddr 2 7FE && echo U-Boot environment... && mmc dev 0 && mmc read $loadaddr 801 800 && mmc dev 1 &&mmc write $loadaddr 801 800 && echo reserved... && mmc dev 0 && mmc read $loadaddr 1001 1000 && mmc dev 1 &&mmc write $loadaddr 1001 1000 && echo Firmware Partition... && mmc dev 0 && mmc read $loadaddr 2001 10000 && mmc dev 1 && mmc write $loadaddr 2001 10000 && echo Root FS... && run root_loop'
  • create the environment variable rootblks16 and set the value accordingly to the size of the RootFS in this case 307MB.

To calculate the value of rootblks16 devide the size of the image in byte by 512 and convert the result into a hex value.

307 * 1024 * 1024 = 321912832
321912832 / 512 = 628736
628736 = 99800HEX 

setenv rootblks16 0x99800
