    v59 v60  
    208208    * Got the mailbox API to work in my bare-metal playground project.
    209209  * Next week: Port the mailbox API to RTEMS with framebuffer support.
     210* **August 2**: Coding Period !#10
     211  * Last week's work:
     212    * Found some edge cases where the mailbox API was breaking. Refactored the code to better support the property channel interface while following the DRY philosophy.
     213    * Figured out that unaligned memory accesses were breaking the API. This is because mailbox messages are unaligned by nature.
     214  * Blocker: The compiler was optimizing two WORD accesses into a single DWORD operation. This was problematic because the messages are not guaranteed to be aligned by nature. Using -malign-strict was the solution.
     215  * Next week: Add framebuffer support.
     216* **August 9**: Coding Period !#11
     217  * Last week's work:
     218    * The mailbox API has been tested and works properly for all tested edge cases. However, the RPi is still not sending framebuffer data to the TV.
     219    * The TV shows a black screen indicating that initialization was successful to some extent.
     220    * Started preparing patches to be merged to master. Patches till UART support are done.
     221  * Blocker: Framebuffer support is hard to debug.
     222  * Next week: Pick up I2C and SPI since framebuffer progress is stuck. Prepare a patch for mailbox support.
