Hi all... My first post... Sry for my english...
I know that LPC2378 is old, I know that SRAM 621024 is old, but i am working with this 2 parts, and need a help.
I work for many year with PIC (18/32) and Arduinos, and now i am starting work with ARM...
I know many things, but i am can't do SRAM and LPC2378 work together. My problem: The EMC configuration not is right... The acces time for this memory is 70ns, and i do this memory work with PIC18F87J50 fine...
Whats happen: I do not know if the problem is in WR or RD operation. After write 65535 bytes, when i will read this 65535 bytes, he stop in addr 1230 or 515 or any other addr, with wrong byte read...
I need help with config in the EMC for memory with 70ns time access. I searched in internet, founded many solutions, for another timings, and I tryed many numbers, any success...
My code is anexed. This code is not final, is only a test:
Cristal 12MHz, PLL 72MHz
