[C2834X] Upload programm to eeprom

Patrick Walther

Hi,

Im trying since weeks to upload my programm to an onboard eeprom.

At the moment i download the programm (here is the code) over UART to the microcontroller and then i write it to the i2c EEPROM.

First i write everything i get from UART to the memory @0x320000 and if i don't recive more data i write it to the eeprom. I only start to write to the memory after i recive the first 0xAA since that is what every file converted by hex2000 seems to have at the start.

To convert the .out file im using the following parameters: hex2000 downloader.out -o downlaoder.bin -b -i2c8 -i2cpsc 29 -i2cclkh 5 -i2cclkl 10

Im uploading the bin file with the "send file" function of TeraTerm.

Hi Patrick,

Are you aware of the specific format of the hex file?

There is a header, and then a series of blocks of data (block size, block address, block data).

What is the specific problem you are having? Are you able to write to the EEPROM?

What do you mean by "specific format" ?

Yes, i can write to the eeprom but the Programm doesn't start after a reboot. (Resistors are set to boot from I2C A1)

Look at the BootRom section of the Technical Reference Manual. The format consists of what I described.
A key, header, and then a number of blocks of data (block size, block address, block data). This is described in our technical reference manuals and user guides.
