Whether CLK_32K can be used for DRA821 Timer module?

Other Parts Discussed in Thread: DRA821

Hi,

      Whether CLK_32K can be used for DRA821 Timer module?

       At present, our project is testing the clock tree. When we test the clock source option of the GPT time module , we find that the clock source of CLK_32K can not generate a timer. If it is a WKUP_HFOSC0 clock source, we do not know whether CLK_32K works properly.

       Add addition, An output clock of WKUP_RC_OSC_12M is further divided down to generate a 32-kHz clock(CLK_32K) through J2100_DRA821_Processor_SR1.0_TRM.pdf.

CLK_32K

CLK_SEL R/W 0h Timer functional clock input select mux control

0h - HFOSC0_CLKOUT
1h - MCU_SYSCLK0 / 4
2h - CLK_12M_RC
3h - MCU_PLL2_HSDIV2_CLKOUT
4h - MCU_EXT_REFCLK0
5h - LFXOSC_CLKOUT
6h - CPSW_GENF0
7h - CLK_32K
Thanks.
