I used PGA309EVM-USB and its software do some enumlate test, after press "contiune" button it can write EEPROM successfully, when I load its output cal results file from "EEPROM" tab "Load EEPROM with file" eveything looks fine, but if I press "Read EEPROM" button, then everything is zeros. Could u show me the reason?
Hi David,
I was able to reproduce a similar issue, where after running the Auto-Cal, the EEPROM was written successfully; however the EEPROM file was not written to the directory, and was not able to load the cal EEPROM txt file. In my case, the issue was related to permissions privileges on the PGA309EMM_USB directory (Windows 10).
The default directory for the PGA309EVM-USB data files is located in the root directory, under C:\Program Files (x86)\proj_PGA309EVM-USB. After navigating to this folder using windows explorer, select /right click the folder, on the menu select 'Properties' and select 'Security' on top menu. To Change Permissions, select the applicable User, click 'Edit' and check mark 'Allow Full Control'. Press 'Apply' and 'OK' as shown on the menus below.
After changing the permissions privileges on the folder, I was able to run the Auto-Cal process, write the EEPROM file and load/read the EEPROM file. In my case, I am able to Load EEPROM txt file successfully and read the EEPROM contents after loading the EEPROM file.
Are you able to run through the process using one of the pre-existing Model Emulator data files?
Many Thanks,
Luis
Able to Load the EEPROM *.txt file, and then read EEPROM contents:
