**** BEGIN LOGGING AT Sat Jun 22 02:59:57 2019 Jun 22 10:41:08 abhishek_ : somehow, I thought that the dma-project included a simple module which exported different pru mems to userspace as char devices. Jun 22 10:54:36 zeekhuge abhishek_ For the time being I added the read, write through /dev/mem as I couldn't compile the DMA kernel driver with the patches; and spent time understanding pru c firmware Jun 22 10:58:42 Okay. Jun 22 21:42:06 julieng: from where to take a value of counter frequency? Jun 22 21:42:41 I mean should it be from device tree? Jun 22 22:35:33 It seems that it should not, since, there is no defined value for clock in the device tree. Jun 22 22:53:05 embden I don't think it is present in the DT. Linux seems to compute it. You should be able to find the codr if you look for cntfreq in mach-omap2 **** ENDING LOGGING AT Sun Jun 23 02:59:57 2019
