Hello,
I need help concerning the low power state with the CC2652R.
We are using a custom pcb for testing purposes. The firmware is based on the empty_mtd example provided and built our application on top of that. Now I measured the current consumption and recognized that there was a steady current of about 1,7mA also when the device should be in deep sleep.
I started debugging and recognized in the registers that all peripherals that I use are closed properly. I looked at the PDCTL0 and PDCTL1 registers. There I saw that the PERIPH_ON was set to 1. After this I saw that the CRYPTO_CLK_EN in the SECDMACLKGDS register was also set to 1. As I do not directly use any crypto driver I looked into the otstack files. The AESECB_handle was not null and I saw that the counter (ref_num) used in aes_alt.c was also set to 1. Because of this I think that the AES driver might be the case why my device cannot go to standby mode.
Does this make sense or may there be any other reason? If it is true, why does the stack does not close this when the devices enters standby?
I am using the latest SDK (5.10) and also the latest CCS version.
Regards
