terra's Issues

Compile script update

Migrate the compile sh script, that generate automatically all firmwares, from TerraVM_ to TerraVM.
See the new AM GROUP_ID that defines the binary path.
Also review some missing file generations.

Version control in the user message structure

This target an opportunity to check if an old script is running in some node.
Add the LSB of VersionId in the usrMsg_t structure (usrMsg.h)

  • Populate the filed when sending a new message
  • On received message, compare with local version ID.
    • If local > received then broadcast a NewProgVersion
    • If local < received then send a reqNewProgBlock 0 to the sender (clear local state fro current script???)
    • No special action if local == received
  • Must review TerraControl

Arduino Mega Original -- Baudrate 57600 doesn't work

When configuring an original Arduino Mega2560 board with BS_BAUD:57600, the computer can't send messages to the board. But this worked with 115200 and 19200.
When using the MegaCore from INHAOS, all three option works fine.

TerraEsp: Exceed Iram0 when compiling with TYPE:BOTH and DEBUG:Y

Interrupt handlers must remain in iram0. The non-OS SDK has very limited space to user application functions.
When compiling with TYPE:BOTH and DEBUG:Y the space is exceeded, the current workaround is disable the DEBUG mode.
New functionalities that need interrupts handlers may be not feasible to be compiled.

*** A new port to the ESP8266 OS-SDK appears to be a good alternative. Also porting together to ESP32 may be possible.
