CC33XX-SOFTWARE: Wrong output when interfacing AM243X-LP and CC33XX-BP

Hi Nivetha,

I would check your in the right boot mode. I would also double check that when you download the FW on the device flash the paths where the cc33_xx.bin files are correct.

Hi Rogelio D,

Thank you for the response.

I changed UDMA 2/2 in example.syscfg of cc33cc_network terminal file. After that i can able to see command for wlan. Now one more issue I'm facing. Could you help with that.

While flashing, the boot mode is UART (switch 1,2,3 are HIGH, rest are LOW). While reading flashed code Boot mode is QSPI(switch 1,6 are HIGH and rest are LOW). 

Everything worked perfectly in SDK 8 version of AM243x. So i canbe sure that all bin files are correct. When i changed SDK version to 10 for AM243x, i got error in UDMA .In cc33xx_network_terminal file, there is a file called example.syscfg file i changed UDMA config to 2/2. Then i got output like below.

Here when i gave wlan_start command it is getting stuck while downloading RAM-BTL . And the version of AM243x is not updated to 10. What could be the issue here? 

Hi RogelioD,

Thank you for the reply.

Previously I asked for the changes while shifting to SDK 10 version of AM243x, they recommended as just need to build the file with version 10 SDK. It should work, like that they mentioned in this forum https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1470930/cc33xx-software-requesting-for-migration-guide-for-am243x-version-10-sdk-to-interface-am243x-lp-with-cc33xx-bp .

So, here I installed SDK 10.01.00.32 for AM243x and i used this SDK 10 to  build the same files of CC33xx_mcu_package_R5. 

Hi Nivetha,

I apologize I was confused on what you meant. Ill try to clarify how it works to hopefully clear up confusion.

The CC33xx_mcu_package is a plugin into the the AM243x SDK. You should be able to use any version of the AM243 SDK thats newer than 8.5.0.24.

Just make sure to change the dependency on the project properties.

However, from the screenshot you shared above. I still believe there is an issue with the binaries that were flashed onto the board.

Can you try running the following section of the user guide again with the binaries found in the R5 release while also importing the examples from the R5 release.

Hi Rogelio,

I tried again by following steps in the getting started guide which you mentioned above. I build all the files afte changing the sdk version and sysconfig version in properties of all files. 

while building 'cc3xxx_network_terminal', first I got error in UDMA. So in example.sysconfig of that file, UDMA was 0/2, I changed it to 2/2. Error got cleared.

Then, I got error like appimage_x509_cert_gen.py file not found. I tracked and changed the path of this file in 'makefile_ccs_bootimage_gen' file. I have attached the file related to those errors below.

Now there is no error in  'cc3xxx_network_terminal' file. 

Then i followed the similar steps which present in getting started guide, but still im getting the same . In COM port, while giving wlan_start command, got stucjed whi;e RAMBTL is downloading.
