Flash写在PIC32MZ上

嗨，我真的迷上了这个。我记得有一段时间，它是有点工作（我进入缓存一致性故障，但基本闪存写入工作…）我的小问题是：我尝试发出一个NOP重置/清除错误标志：NVMCONBITS。WREEN＝0；NVMCONBITS.NVMOP＝0；NVMKEY＝0x0；NVMKEY＝0XAA99 665；NVM；NVMKEY＝0x55 66 .99；NVMCONSET＝1和lt；lt；15；也尝试（这只是一个库的片段）：NVMCON＝OP；& lt；-这里OP= 0x4000；NVMKEY＝0xAA96955；NVMKEY＝0x55 66 99 AA；NVMCONSETSET 0x8000；一些库/实例加载NVMKEY＝0x0；第一，一些没有。我尝试了两种方式。第四，但我总是把Wrrr设置为一次我设置WR。可能是我的一些配置设置阻止闪光灯工作吗？我不使用DMA，也不中断。（也尝试了DMA/Its禁用它们的代码，但结果相同……如果有人知道我应该在哪里寻找问题，请让我知道。THX，爱德华·艾尔利克

    Hi,

I've got really stuck with this one. And i remember there was a time when it was somewhat working (i got into cache coherency trouble, but the basic flash write was working...)
My little problem is this: I try to send out a NOP to reset/clear error flags:

NVMCONbits.WREN = 0;
NVMCONbits.NVMOP = 0;
NVMKEY = 0x0;
NVMKEY = 0xAA996655;
NVMKEY = 0x556699AA;
NVMCONSET = 1 << 15;

also tried (this is just the snippet from a library):
NVMCON = 0;
NVMCON = op;          <-here op = 0x4000;
NVMKEY = 0xaa996655;
NVMKEY = 0x556699aa;
NVMCONSET = 0x8000;

Some libraries/examples load NVMKEY=0x0; first, some doesn't. I tried both ways back and forth, but i ALWAYS get WRERR set to one once i set WR.

Could it be that some of my configuration settings preventing flash to work? I use no DMA and no Interrupts. (also tried the code which has DMA/Ints disable in them but same results...

If someone has some idea where should i look for problems, please let me know.

thx,
Edo
