H5 has a mix of problems. One, shared with H3 _was_ this: https://marc.info/?t=159333011500004&r=1&w=2 Now is solved. Other one is this: https://marc.info/?t=160451196500005&r=1&w=2 Read the corrections in my second mail (too much coffee). The dtb doesn't have an opp table, and the frequency set by u-boot is wrong. I don't know why they are doubling the freq: ./arch/arm/mach-sunxi/dram_sunxi_dw.c: if (socid == SOCID_A64 || socid == SOCID_R40) { clock_set_pll11(CONFIG_DRAM_CLK * 2 * 1000000, false); clrsetbits_le32(&ccm->dram_clk_cfg, CCM_DRAMCLK_CFG_DIV_MASK | CCM_DRAMCLK_CFG_SRC_MASK, CCM_DRAMCLK_CFG_DIV(1) | CCM_DRAMCLK_CFG_SRC_PLL11 | CCM_DRAMCLK_CFG_UPD); } else if (socid == SOCID_H3 || socid == SOCID_H5 || socid == SOCID_V3S) { clock_set_pll5(CONFIG_DRAM_CLK * 2 * 1000000, false); clrsetbits_le32(&ccm->dram_clk_cfg, CCM_DRAMCLK_CFG_DIV_MASK | CCM_DRAMCLK_CFG_SRC_MASK, CCM_DRAMCLK_CFG_DIV(1) | CCM_DRAMCLK_CFG_SRC_PLL5 | CCM_DRAMCLK_CFG_UPD); } ====================== ./arch/arm/mach-sunxi/clock_sun6i.c: /* PLL5 rate = 24000000 * n * k / m */ if (clk > 24000000 * k * max_n / m) { m = 1; if (clk > 24000000 * k * max_n / m) k = 2; } writel(CCM_PLL5_CTRL_EN | (sigma_delta_enable ? CCM_PLL5_CTRL_SIGMA_DELTA_EN : 0) | CCM_PLL5_CTRL_UPD | CCM_PLL5_CTRL_N(clk / (24000000 * k / m)) | CCM_PLL5_CTRL_K(k) | CCM_PLL5_CTRL_M(m), &ccm->pll5_cfg); ====================== The problem with the orange pi one, lite, etc is that the regulator can't match the opp table (based on the soc, not the board) because there is no gpio regulator driver, the code is split among functions... well read the mail: https://marc.info/?l=openbsd-tech&m=159484418907996&w=2 I was thinking about writing a simple driver, but I have little little time, I'm not an openbsd developer and no one shown interest. In fact I'm felling really stupid searching the archives for my own mails. With the changes I suggested these boards work great. Just add some cooling if you want to stressed them. adr. P.S. I don't understand how can't you find this on the list archives. Really.
