External Flash reading Error

[nikhilvv07]

Hello..

Am interfacing dsPic33FJ128gp708 MCU with SST25VF016B flash memory.

Flash memory is using to store image's code created by using VTFT software. The stored Image is displaying directly to tft display.

by using TFT library function / **** TFT_Ext_Image(0,0,0x1a6100,1) ***/ to access flash memory location i am able to get the stored image on display till a perticular memory location may be till 0x1FFFFF.

after this memory location (Not sure about the border address) it showing white screen or some time it shows black screen.

Is there any limit to in tft_ext_image() ? if not why it is happening?

please help to resolve this issue.

Library version is unknown. Dont know how to get it.

Hello,
It appears that you reached the maximum capacity of your flash memory: 16 Mb (megabits) = 2 MB (megabytes), and the last memory address of your chip should be - 0x1FFFFF.
Try reducing the size of the image if possible and see if that helps.
