JTAG for EEPROM

Hello. Please clarify my doubts given below:
1) Is it necessary to have Seggar JLink Debugger to load a program to an externally I2C connected EEPROM?
2) Can we use UART connected at P0_4 and P0_5 to download a program to the I2C EEPROM connected to the Port 0_1 and P0_1 pins of the WLCSP package?
If not then is there any other alternative for this?

Hi Arun:

Hi Arun:

Q1: No

Q2: I guess you want use Port 0_1 and something else, not the same pin.

For EPROM programming we download a small program on to Cortex M0 to perform the EEPROM programming. This program is configured to access EEPROM on our kits on specific pins. If you need to access EEPROM using other pins you will have modify this program accordingly. The source code for this program is included in the SDK under "tools" folder.

For general information relating to this topic, please refer to document "AN-B-023 - DA14580 interfacing with external memory v1.0.pdf", available under "Resources" tab of this website.

Thanks,

Thank you so much. I mistyped

Thank you so much. I mistyped it and the actual pins used for EEPROM are port0_0 and p0_1. In the AN-B-023 document i came to see the interface with the I2C EEPROM. I hope this confirms to load the program to external I2C EEPROM though the UART. Please clarify if any changes are there in this.
