sw: mikrobus: add mikrobus click ID flasher as submodule #60

Closed vaishnavachath closed 3 years ago

vaishnavachath commented 3 years ago

This project allows to flash the eeprom on the new mikrobus click ID adapter from BeagleConnect Freedom,

The scheme for writing manifests is as follows:

  1. write production manifest(fixed, minimum information for enabling through userspace if driver is available) at addr 0x0000 onwards
  2. write variable manifest at next free block after writing production manifest
  3. update eeprom bytes with production manifest start block
  4. write protect fixed/production manifest(currently commented)

production/fixed manifest :

manifest available at click production time(contains some mikroe specific strings also), if driver does not exist at production time,it will contain minimal information on click hardware to enable for development through userspace, if driver exists additonal greybus/mikrobus information will be present

variable manifest :

vaishnavachath commented 3 years ago

For flashing mikrobus click ID EEPROM with a click manifest, perform:

./flash-clickid.sh RTC-6-CLICK {or any other click with manifest available in manifests directory}

from sw directory after plugging in the click ID adapter on the mikrobus port 1(USB, Battery Connector Side) on BeagleConnect Freedom

Tested over greybus (BeagleConnect Rev C3 2.4G) :
