LPC4337 EMC initialization and RGU

atsuyosano — Tue, 09 Sep 2025 07:21:18 GMT

Hello.

I'm developing with the LPC4337. EMC initialization:
Chip_EMC_Dynamic_Init((IP_EMC_DYN_CONFIG_T *) &IS42S32800D_config);
Chip_EMC_Static_Init((IP_EMC_STATIC_CONFIG_T *) &fpga_config);

However, when I initialize Timer1 after this, the EMC doesn't work properly. Chip_RGU_TriggerReset(RGU_TIMER1_RST);

If I comment out the Timer1 initialization, it works properly.
Why is this?

こんにちは。

LPC4337 で開発を行っています。EMC初期化。
Chip_EMC_Dynamic_Init((IP_EMC_DYN_CONFIG_T *) &IS42S32800D_config);
Chip_EMC_Static_Init((IP_EMC_STATIC_CONFIG_T *) &fpga_config);

ところがこの後 Timer1 の初期化を行うと EMCが正常に動作しません。 Chip_RGU_TriggerReset(RGU_TIMER1_RST);

Timer1 の初期化をコメントアウトすると正常に動作します。
なぜでしょうか

Hello @atsuyosano

Please try to initialize the timer before initializing the EMC.

Also, check whether the timer interrupt is enabled. If it is, please try to disable the interrupt first.

If the issue persists, please send your project and I'll help you check it.

Thank you.

Alice
