  2. # Board configuration file for the Freescale IMX6Q Sabre SD EVM

  3. #

  4. # This board does not have an embedded JTAG adapter, you must source

  5. # a suitable adapter configuration before sourcing this file.

  6. 

  7. # Sabre SD has a standard ARM-20 JTAG connector with

  8. # nTRST and nSRST available.

  9. reset_config trst_and_srst

  10. 

  11. # the only possible transport is JTAG

  12. transport select jtag

  13. 

  14. # iMX6Q POR gates JTAG and the chip is completely incommunicado

  15. # over JTAG for at least 10ms after nSRST is deasserted

  16. adapter srst delay 11

  17. 

  18. # Source generic iMX6Q target configuration

  19. set CHIPNAME imx6q

  20. source [find target/imx6.cfg]

  21. 

  22. # function to apply initial configuration after a reset. It

  23. # provides a basic pad configuration and also DDR memory and clocks

  24. # sufficient to load and execute a boot loader (e.g. barebox) from

  25. # DDR memory. This list is extracted from the barebox flash image

  26. # header.
