DSP怎么样进行ISP升级、或者IAP？
有没有人做过DSP的 bootloader 。麻烦给一个参考的。感谢了！做过stm32的多个bootloader，dsp的第一次弄 资料好少 贴一个CMD文件。工程就不上传了，公司电脑文本都被加密过的/*

/* Define the memory block start/length for the F2803x
PAGE 0 will be used to organize program sections
PAGE 1 will be used to organize data sections
Notes:
Memory blocks on F2803x are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.
L0/L1/L2 and L3 memory blocks are mirrored - that is
they can be accessed in high memory or low memory.
For simplicity only one instance is used in this
linker file.
Contiguous SARAM memory blocks can be combined
if required to create a larger memory block.

第一步就是CMD要改好，FLASH分APP区和BOOT区，BOOT跳转地址是0x3F7FF6，这个是硬件上电自动跳转的，APP跳转地址0x3F5FF6 这个是自己指定的。
FLASHAPP : origin = 0x3E8000, length = 0x00BFFC /* on-chip FLASH */
APPSTART : origin = 0x3F5FF6, length = 0x000002 /* on-chip FLASH */
FLASHBOOT : origin = 0x3F6000, length = 0x001F80 /* on-chip FLASH */
BEGIN : origin = 0x3F7FF6, length = 0x000002 /* Part of FLASHA.Used for "boot to Flash" bootloader mode. */
FLASH的擦除，烧写TI有提供API。跳转函数
void JumpToApp(void)
{
((void(*)())0x3F5FF6)();

你好 ！非常感谢。看来和stm32的差异很大。这个CMD填写地址他会自动跳转是吗？我有一个疑问就是。这个bootloader 是需要自己写吗？？还是自带的？ toptrying 发表于 2023-8-8 09:04

这样就没办法不拆外壳 下载了。目前只想 不拆可下载 。需要硬件IO口的话那需要外壳留孔。这样还不如直接留一个下载口的孔。{:lol:} 。这是不是很多都自己开发bootloader的原因吧 jaywen 发表于 2023-8-9 17:47

你好请教下。我按照手册。上电前对GPIO24拉低、同时拉高GPIO32。上电的确进入了boot。因为应用程序没有运行的。然后用C2pro进行串口(SCIA)下载数据。然后看串口线 有灯闪速一下说明应该有数据返回，dsp好像马上进入了应用程序中。C2pro显示超时，下载失败。附上截图。和芯片手册。dsp型号：tms320f280049。 jaywen 发表于 2023-8-18 16:42

那个已经是处于boot了。难道需要重新上电下才可以继续下载？ 楼主解决了吗，硬件实现还是软件实现 llgz 发表于 2023-9-13 09:52
楼主解决了吗，硬件实现还是软件实现
(引用自18楼)
没有解决 进入了 boot 但是一直下载不了程序 串口线2、3有没有可能搞错？USB转串口还是电脑自带RS232串口？GPIO24=0、GPIO32=1状态下，先PROGRAM下载，然后板子加电试试。这个软件tms320f28035用了很长时间没有问题的
