Other Parts Discussed in Thread: LAUNCHXL-F280049C
Hi all,
I am trying to figure out how to use the i2c bootloader with 24AA eeprom. So far I have managed to create boot image with the HEX200 Utility (with these parameters --boot --i2c8 --i2cclkh=43 --i2cclkl=43 --i2cpsc=0 --binary) and to program the eeprom with it. The bootloader starts successfully in emulation mode: I am writing 0x5AFFFF20 @ 0xD00 and 0x4703 @ 0xD04 which means to boot from i2c if GPIO32 is HIGH and boot from flash if LOW. Everything works as expected (the newly loaded program runs successfully) with the exception that the I2C CLK signal is not 100 KHz but close to 1 MHz !?! The ROM Code and Peripheral Booting chapter of the manual states that the i2c clock should be set to100 KHz from the bootloader but i am observing 1 MHz when the loading start. My platform is the LAUNCHXL-F280049C MCU025B.
