MX_Master Posted May 16, 2021 Share Posted May 16, 2021 I'm trying to use H6's ARISC (CPUS) core for my CNC project https://allwincnc.github.io/ There are no problems to switch ARISC (CPUS) clock source using H3 and H5 (latest Armbian Buster). I'm using R_PRCM (0x01F01400) > CPUS_CLK_REG (offset 0x0000) register to switch clock source to the PERIPH0 PLL. For the H3 I'm using uboot script, for the H5 - own kernel module. But for the H6 this register (R_PRCM) isn't properly documented. Found out this register was moved to the 0x07010000. But modifying this register at offset 0x0000 doesn't take any effect. Just checked this using uboot cmd and own kernel module. I need your help. guys. Any suggestions how to switch H6's ARISC (CPUS) clock to the PERIPH0 PLL? Is it possible this memory region is protected from uboot and linux kernel? 0 Quote Link to comment Share on other sites More sharing options...
