Failed to identify the chip #1

Closed idoodler closed 3 years ago

idoodler commented 8 years ago

I want to use this tool to flash a CC1110 chip, but somehow I am not able to identify the chip. Because 2 of the default GPIO pins were already in use I changed the pins. I already tested the pins with "/sys/class/gpio/" manually and they go high and low as expected, but they do not work with ccdbg. Am I required to use the pins defined by you?

Thanks!

Hi! Unfortunately, the ccdbg tool is only verified and enabled to work on CC2530, CC2531, CC2533, CC2540, and CC2541. I'd like to add support but I am busy with work now and I don't have a CC1110 chip to experiment with. If you like, you can contribute to the project. ccdbg.* need to be modified. I can help if you have specific questions regarding the implementation.

For the RPi interface, definitions for RESET, DC, and DD in ccdbg-rpi.cpp should be changed as required. I think you did this already.

A few days passed and I decided to use an Intel Edison instead of an Raspberry Pi. The application can be compiled without any issue which is great:) To add support for the CC1110 chip I added the chip ID 0x01 to the ccdbg.h enum, I also added it to the chip array in ccdbg.c with a flashPageSize of 1. The ID and the flashPageSize are from here But it still fails. I checked the ccdbg_command() function and noticed, that the readByte() always returns 0. I double checked the wiring and I can't find an issue.

Do you have an idea how to solve this issue?

I think I figured it out. The Intel Edison GPIO pins operate with 1.8V, the CC110 chip breakout I am using operates with 3.3V. I need a level converter.
