µVISION: INCORRECT ON-CHIP XRAM FOR ST UPSD DEVICES
Information in this article applies to:
I am using the STMicroelectronics uPSD3233B and the data sheet says the on-chip XRAM is located at address X:0XFF00 - X:0xFFFF. However, when I use the Keil Device Database to select the uPSD3233B and select Project - Options for Target "Target filename" - Target, the Use on-chip XRAM box has address X:0x00 - X:0xFF. Which is correct and how do I use the on-chip XRAM?
The data sheet is right. See the resolution section below to fix the problem.
The Internal XRAM address for the ST uPSD3233 chips in the device database was incorrectly set to (0x00-0xFF).
This should fix the problem for uV version 2.3.0. Future revisions will correct this.
