Hi Bernhard, Resend this mail with CCing mail list so that more people can see this issue and may have answer. Also correct register access code I use as I send wrong version code in last mail.
I see sunxi-tool patch a3ce5f9f and you also mentioned that writing value is OK with register based method in google group. Do you have eFuse writing code that works? I can write OEM_PROGRAM and THERMAL_SENSOR with below code. But when I write ROTPK_HASH, eFuse is not changed. https://linux-sunxi.org/SID_Register_Guide#eFUSE 151 iowrite32be(val, sid->base + SUN8I_SID_PRKEY); 152 /* Set word, lock access, and set read command */ 153 reg_val = (offset & SUN8I_SID_OFFSET_MASK) 154 << SUN8I_SID_OFFSET_SHIFT; 155 writel(reg_val, sid->base + SUN8I_SID_PRCTL); 156 reg_val |= SUN8I_SID_OP_LOCK | SUN8I_SID_WRITE; 157 writel(reg_val, sid->base + SUN8I_SID_PRCTL); 158 159 ret = readl_poll_timeout(sid->base + SUN8I_SID_PRCTL, reg_val, 160 !(reg_val & SUN8I_SID_WRITE), 100, 250000); 161 if (ret) 162 return ret; 163 164 writel(0, sid->base + SUN8I_SID_PRCTL); Best Regards.
