Hi all,
I am using LPCOpen last revision with on a LPC1788 with external SDRAM configured as RBC (Row Bank Column).
I have found that there is a bug when configuring SDRAM mode register, according to the LPC1788 user manual:
Quote:
Determine the shift value OFFSET to shift the mode register content by. This shift
value depends on the SDRAM device organization and it is calculated as:
OFFSET = number of columns + total bus width + bank select bits (RBC mode)
OFFSET = number of columns + total bus width (BRC mode)
The bank select bits are never added to the Col_len variable in initDynMem() function so the mode register is wrongly initialized.
