全志R128来袭，有想入坑的吗?我先来点初步研究成果

xboot · 2023-05-13 10:01:58

全志R128里面有三个核心，一个M33,一个C906，还有一个DSP。

M33核主要负责引导，启动，安全，休眠，唤醒，低功耗，WIFI/BT等相关功能。
C906主要负责运行各种APP，控制各种外设驱动
DSP主要负责音频算法处理

现在手上拿到了一个有异常的板子，无法正常烧录，刷机，但fel模式是可以运行的。所以先尝试开发xfel对R128芯片的支持。

适配xfel，前面比较顺利，可以顺利读写SRAM，但exec命令被卡壳了，无法运行ARM payload，经过不断尝试，终于可以执行exec指令了，原来M33核的payload每一条指令不一定都是32位，有可能存在16位的，M33核无法编译出全32位指令。

虽然算是搞了exec指令，但如何可靠稳定的执行自己写的测试程序，现在测试下来，感觉还是有点怪意，初步分析，可能M33核心里面指令或者数据cache了，还没玩过M33，对这个核里面的细节不清楚，先不枉下结论了，但这个问题，是有必要去深究的。

R128里面有PSRAM，有nor flash。初步计划，针对R128芯片，后续xfel需要开发以下功能：

1，读写SRAM，（已完成）
2，执行运行在M33核的payload指令（已完成）
3，读取R128的SID（已完成）
4，初始化M33核心的jtag接口，此接口跟调试串口复用（已开发，未测试）
5，实现reset操作
6，初始化LSPRAM以及HSPSRAM
7, 支持启动C906核心，加载并执行通过write命令写入到RAM中的C906程序
8, 支持启动DSP核心，加载并执行通过write命令写入到RAM中的DSP程序 (优先级低，估计没手段验证)
9，支持烧写NOR FLASH

如果完美实现了这些功能，通过xfel来开发R128，估计要爽到飞起，开发验证都是足够便捷的。

已实现RS128，PSRAM的初始化

xfel ddr r128-s1 - Initial PSRAM controller for R128-S1
xfel ddr r128-s2 - Initial PSRAM controller for R128-S2
xfel ddr r128-s3 - Initial PSRAM controller for R128-S3

xfel ddr r128-s2

执行初始化指令后，就是访问LSPRAM以及HSPSRAM了

xboot · 2023-05-14 21:16:11

关于exec指令如何可靠稳定的执行自己写的测试程序的问题，经过深入研究，定位是M33核指令缓存相关问题。

我们编写的payload，如果上传到某个地址，然后在这个地址执行后，这部分代码就被缓存了，如果这个时候，我们在更新另外一个payload，通过write指令写入内存，SRAM或者LSPSRAM或者HSPSRAM中，然后新payload的执行地址如果跟原先的地址相同的话，这个时候就会出现不可预见的现象，执行的指令有可能是原先被缓存过payload。

既然分析到问题点了，解决手段，有两种方案：

一种是粗暴的关闭指令缓存，这种方案影响后续的执行效率，就不考虑了

另一种方案就是现在采用的方案，每一个payload保证开始的指令都是一致的，而且这些一致的指令里，首先做的动作就是清理指令，这样就能保证每个payload都能有效执行了，避免不可以预见的现象。

payload头指令

.syntax unified

	.global _start
_start:
	dsb.w sy
	isb.w sy
	ldr.w r0, _iciallu
	mov.w r1, #0x0
	str.w r1, [r0]
	dsb.w sy
	isb.w sy
	b.w reset
	.align 2
_iciallu:
	.word 0xe000ef50

reset:
	push.w { lr }
	/* ... */
	pop.w { lr }
	bx lr

经过以上处理后，就可以解决之前感觉怪意的问题，同时也验证了，payload放在LSPSRAM或在HSPRSRAM空间，都是可以正常执行的，不是必须是内部的SRAM。这就为后续的全RAM中执行程序，打下基础。什么M33程序，C906程序，DSP程序，理论上都是可以执行的。

xboot · 2023-05-14 21:40:20

有了上面的研究，我们就可以编写一个纯粹的针对cortex-m33核的read32以及write32的payload了，为何要自己编写这两个payload，而不采用fel协议自带的读写R32，W32实现，是因为fel协议本身在读写内存时，是基于字节访问的，而某些控制器的寄存器是不支持字节访问，只支持word字访问，因为有这种限制，那fel自带的读写函数，是不适合操作芯片寄存器的。

封装读写payload

static uint32_t payload_read32(struct xfel_ctx_t * ctx, uint32_t addr)
{
	static const uint8_t payload[] = {
		0xbf, 0xf3, 0x4f, 0x8f, 0xbf, 0xf3, 0x6f, 0x8f, 0xdf, 0xf8, 0x14, 0x00,

	};
	uint32_t adr = cpu_to_le32(addr);
	uint32_t val;

	fel_write(ctx, ctx->version.scratchpad, (void *)payload, sizeof(payload));
	fel_write(ctx, ctx->version.scratchpad + sizeof(payload), (void *)&adr, sizeof(adr));

利用读写payload实现使能jtag的pinmux功能

static int chip_jtag(struct xfel_ctx_t * ctx)
{
	uint32_t addr;
	uint32_t val;

	/* Config PA16 and PA17 to SWD-TMS and SWD-TCK */

	val = payload_read32(ctx, addr);
	val &= ~(0xf << ((0 & 0xf) << 2));
	val |= ((0x8 & 0xf) << ((0 & 0xf) << 2));
	payload_write32(ctx, addr, val);

	val = payload_read32(ctx, addr);
	val &= ~(0xf << ((1 & 0xf) << 2));
	val |= ((0x8 & 0xf) << ((1 & 0xf) << 2));
	payload_write32(ctx, addr, val);

	return 1;
}

再接再厉，利用读写payload操作M33核的看门狗，实现reset功能。

static int chip_reset(struct xfel_ctx_t * ctx)
{
	payload_write32(ctx, 0x40020400 + 0x14, (0x16aa << 16) | (0x1 << 0));
	payload_write32(ctx, 0x40020400 + 0x18, (0x16aa << 16) | (1 << 0));
	payload_write32(ctx, 0x40020400 + 0x10, (0xa57 << 1) | (1 << 0));
	return 1;
}

关于R128 M33核的thumb指令，有个特别要注意的地方，如果你编写的M33程序入口地址就是thumb指令，那么执行地址的最低位要置1，这样M33核才开始执行2字节的指令，否则当成4字节的指令，此问题需要特别注意，否则调试会让你调得怀疑人生。

比如rt_system.bin的入口地址是0x08004000，那么执行地址就是0x08004001

xfel write 0x08004000 lichee/rtos/build/r128s2_pro_m33/img/rt_system.bin;
xfel exec 0x08004001

最近编辑记录 xboot (2023-05-16 19:17:22)

xboot · 2023-05-16 19:25:35

用xfel指令加载sdk默认镜像试验。

#初始化DDR
xfel ddr r128-s2;

#加载M33核程序到0x08004000
xfel write 0x08004000 lichee/rtos/build/r128s2_pro_m33/img/rt_system.bin;

#加载C906程序到0x08200000，注意此程序是SPI NOR XIP的，光加载到RAM中是无法完整运行的，这里仅做引导C906试验。
xfel write 0x08200000 lichee/rtos/build/r128s2_pro_c906/img/rt_system.bin;

#运行M33核心程序，M33核心运行时，会自动的运行C906以及DSP程序。所以，将C906和DSP程序准备好，可以随着M33核一起启动。
xfel exec 0x08004001

已实现xfel烧写R128内部SPI NOR FLASH，但出现了一个超级超级大的坑。

只要用xfel访问过的R128芯片，哪怕仅仅是探测下spi nor flash，就会导致全志的固件无法正常运行，而且这个时候想用Phoenixsuit工具去刷机也不给刷了，提示找不到spi nor flash，但用xfel是可以正常读写spi nor flash的，这坑坑。。。。

换句话说，xfel能将R128搞残，而且是永久性的，这。。。。

全志固件启动的提示：

手上仅有的2片R128都被搞残了。再贴个xfel烧写spi nor 的log吧，读写spi nor完全正常，校验也可以通过。

高内存版本是有可能代替F1C100S的，但现在还没见到R128-S3的芯片

lanlanzhilian 说：

这会不会是读写的姿势不对

初步怀疑是spi flash只要一被unlock了，全志的sdk固件就无法正常运行，包括烧录，如果确定是这个原因的话，那就是全志SPI NOR FLASH驱动问题了，而且这段代码还在闭源的boot0里，你想修这bug都没门。80%的可能性是这个问题导致的。

xboot · 2023-05-23 12:04:09

确认是R128芯片内部的SPI NOR FLASH只要处于unlock的状态，就无法正常启动，而且也无法烧录，这个问题全志肯定要去解决了，不然wifi芯片，只要被攻击了，可以造成所谓的物理损坏，让产品直接宕机，类似于多年前的bios病毒，可以将主板搞挂

xboot · 2023-05-23 12:49:58

严谨点说，就是多做3个操作，R128芯片内部spi nor flash必挂

1, 全局解锁SPI NOR FLASH
2, 将状态寄存器2，清零
3，将状态寄存器3，清零

具体是哪一个操作导致的，还是3个操作共同导致的，就不得而知了，每实验一次，一个芯片就报废了，我手上的三颗芯片，全处于搞残的状态，已经没有新芯片了，这些实验代价有点高。

除了这三个操作，xfel在操作spi nor时，还会执行两个动作
1，复位SPI NOR FLASH
2, 将状态寄存器1，清零

这两个动作是不会产生任何副作用的，在R128上已测试通过，就是最上面的三个步骤，会导致问题，而且百分百必现。

再去锁定下SPI NOR FLASH，可以救活被搞残的芯片？

经测试，是状态寄存器2里面的QE位，如果这个bit被清零了，那么内置的spi nor flash就无法引导了，而且也无法烧录，这个状态寄存器是掉电不丢失的，永久保存，除非再次修改。

xboot · 2023-05-23 15:08:08

只要将这个比特重新写回1，就可以救活，R128内部的SPI NOR FLASH

xboot · 2023-05-23 23:30:37

xfel升级到V1.3.1版本，此版本已完整支持R128，楼上计划的所有功能均以实现，包括烧写SPI NOR FLASH，通过fel启动RISCV核心，启动DSP核心。

这里扩展了一个extra命令，可以启动RISCV和DSP核，后面的地址，就是核心的入口地址。

usage:
    xfel extra exec riscv <address> - Boot riscv and jump to address
    xfel extra exec dsp <address>   - Boot dsp and jump to address

现在运行xboot有两种方案：

1,直接用xfel来运行RISCV程序

xfel ddr r128-s2;
xfel write 0x08200000 xboot.bin;
xfel extra exec riscv 0x08200000;

2,利用全志SDK里的m33.bin程序来引导riscv

xfel ddr r128-s2;
xfel write 0x08004000 lichee/rtos/build/r128s2_pro_m33/img/rt_system.bin;
xfel write 0x08200000 xboot.bin;
xfel exec 0x08004001;

xboot · 2023-05-23 23:32:24

对于前面遇到的SPI NOR FLASH清除QE比特导致的无法启动烧录问题，这里在xfel做了修正，直接删除写状态寄存器2及状态寄存器3的擦作。

xboot · 2023-05-24 09:38:42

贴一个采用xfel直接引导xboot的完整log，可以是空片直接启动。

xfel ddr r128-s2;
xfel write 0x08200000 xboot.bin;
xfel extra exec riscv 0x08200000;

带宽跟主频比较相关，可能是cache的原因

这个现象比较奇怪，板子问题？又不太像，可以linux下面试一试。看是否能探测成功。

那估计你就得怀疑你的硬件了
