Hi NXP community


I am using LPC546xx and have found a mismatch between the SDK 2.5.0 and User Manual UM10912 concerning static and dynamic memory regions depending on Cip Select:


Static Memory Chip Select Base address

CS0: 0x8000'000 (UM10912) vs 0x8000'0000 (SDK)

CS1: 0x8800'000 (UM10912) vs 0x9000'0000 (SDK)

CS2: 0x9000'000 (UM10912) vs 0x9800'0000 (SDK)

CS3: 0x9800'000 (UM10912) vs 0x9C00'0000 (SDK)


Dynamic Memory Chip Select Base address

CS0: 0xA000'000 (UM10912) vs 0xA000'0000 (SDK)

CS1: 0xA800'000 (UM10912) vs 0xB000'0000 (SDK)

CS2: 0xB000'000 (UM10912) vs 0xC000'0000 (SDK)

CS3: 0xB800'000 (UM10912) vs 0xD000'0000 (SDK)


Which one is the correct one? SDK or User Manual?
