hi, I'm using a custom designed board having LH79520 with 32MB micron SDRAM & 8MB flash. Very similar to LogicPD board, but without the extras (lan, audio, CPLD, buffers etc). It does have a external reset chip.
The board works fine when no interrupts are used. However, when I try to use the timer interrupt, it works intermittently between power-ups. Meaning, the interrupt is working after a power-up on some occasions and doesn't on other occasions. But once the interrupt starts to work after a power-up, it will keep working until the next power cycle to the board. I've verified that the timer itself is configured properly and always counts, irrespective of whether interrupt is working or not.
I'm using standard Sharp ABL/CSP/BSP software package.
