Hi all,
I'm having an issue with writing the EEPROM on an atmega328pb. I'm using a USBtiny.
I can write to the flash memory with no issues. However, when I try to write the EEPROM, I get the following:
avrdude -patmega328pb -cusbtiny -Ueeprom:w:application.eep avrdude: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.00s avrdude: Device signature = 0x1e9516 (probably m328pb) avrdude: reading input file "application.eep" avrdude: input file application.eep auto detected as Intel Hex avrdude: writing eeprom (205 bytes): Writing | ########################## | 51% 20.81s avrdude: error: usbtiny_send: error sending control message: Connection timed out (expected 128, got -110) Writing | ################################################## | 100% 22.12s avrdude: 205 bytes of eeprom written avrdude: verifying eeprom memory against application.eep: avrdude: load data eeprom data from input file application.eep: avrdude: input file application.eep auto detected as Intel Hex avrdude: input file application.eep contains 205 bytes avrdude: reading on-chip eeprom data: Reading | ################################################## | 100% 5.37s avrdude: verifying ... avrdude: 205 bytes of eeprom verified avrdude: safemode: Fuses OK (E:FF, H:DE, L:CE) avrdude done. Thank you.
Consistently, at 50% or 51% complete, an error occurs. The second progress "Writing" bar that goes to 100% fills almost immediately, as does the "Reading" progress bar.
Other information:
- The EESAVE fuse is not programmed, I don't believe this affects the writing of the EEPROM itself?
- Using avrdude to dump the EEPROM suggests that it has actually been written successfully.
- I'm using avrdude version 6.3
Despite an apparently successful write, I'm concerned there might be issues I'm not aware of, and in general I'd like my tools and processes to be error free!
Can anyone offer any suggestions or advice?
