Hi Dialog.
I have connected an eeprom to my expert dev kit (scl --> P02, sda-->P03). I also connected 4k3 pullup resistors at scl and sda pins. I have two questions about it.
1) When i read the eeprom with Smart Snippets i dont get the same data i wrote. I read in another topic that this is normal and it happens because of the hex to bin conversion. Is that correct?
2) I cant boot from the eeprom. I successfully downloaded my hex file to eeprom but i cant boot from the eeprom. Should i remove the usb cable and jtag and power the da14580 from battery to boot from eeprom?. .. Is there anything else i should do?
提前谢谢!

Hi Kostakis
1) What do you mean you don't get the same data, are the data shifted or they are completely different ? Are you connected to smartSnippets using uart or jtag ? If you are connected with uart try to connect with jtag and see the results when reading your eeprom.
2) It would be a good practice after you 've downloaded the firmware to remove the jtag and to power off the da14580 in order to boot from eeprom.
Thanks MT_dialog
They are completely different. I am connected using jtag! Is that my problem? Could you recommend an eeprom chip that works fine with da14580?
Hi Kostakis
I dont think that jtag is your problem,
something must be wrong with the downloading procedure to the eeprom, please have a look the doc AN--B-023 interfacing with external memory. The document suggests the I2C M24M01-RMN memory for the expert kit.
Thanks MT_dialog
Ok. Thank you. I will try the memory you suggested and i hope it will work.
