However, I am glad the serial port method is available. Not a big problem to get to find the location on the pcb, per https://www.mobileread.com/forums/showthread.php?t=49942 but I am not clear whether it's OK to use 3.3V levels or the 1.8V that the K3 needs.
Thanks for the advice, I feel like I have a direction and a road to follow... |
Alright, I admit it, I have read parts of the manual.
It is 1.8v low voltage serial, same as the other Freescale parts.
Even before finding the "magic button" to enter downloader mode - -
Somebody set a standard for description:
"serial port method" is too general.
Since the serial port may be:
Used for manual interaction with the Kindle firmware (it is **both** the U-Boot port and the Kernel's console port) ;
Used for interaction with "down loader mode" of the Freescale part by :
The Freescale Advanced ToolKit (ATK) ;
The K3Flasher (once modified to include the i.MX31 setup) ;
Other, general purpose, serial communications *nix tools (like expect).
That is at least four methods, any one of which could lay claim to the phrase: "serial port method".
