my pagesize is 256 bytes, and 90k is about 351 pages for(i = 0; i < pages; i++) { W25qxx_ReadPage((uint8_t *)u32_databuf, EXT_FLASH_ADDR_APP_START + i,0, w25qxx.PageSize); ProgramInternalFlash(APP_BASE_ADDR + i * w25qxx.PageSize, u32_databuf,...

I set the application code @0x08004000 in the icf files and also set the invect table to this address. i shut down all ISR before jump, but it still fail to jump my app code.

Thank you for your advice. i have moved all erase code before write code. firstly i EraseInternalFlash(APP_BASE_ADDR,APP_LENGTH ); erase all my app code.

i use the code below follow the code examples on page938 of RM0376 Reference manual , it will reduce the time to 9 seconds.The note was under the code Note: This function must be loaded in RAM. I'm not sure can this code run in flash? and why only pr...

is there any DMA code to move memory to internal flash code example or use interrupt for flash code?

ZXiao.1 · 2021-05-26

No, I have comment the code W25qxx_ReadPage, the result is same.

ok, thanks a lot. you mean read the RCC registers can know what happened now about the RTC clock?

I use HAL_FLASH_Program to program my internal flash, but it takes too much time, I program about 90kbytes, it will take about 90 seconds. Is there any faster way to program stm32l072.

It always work ok for RTC. But sometimes HAL_RTC_MspInit retrun me HAL_TIMEOUT, which case would cause this error? I did not change my hardware and firmware for RTC, I use the internal clock for rtc.

Now i'm using the stm32l072CBT6 mcu to do a bootloader, but I cannot jump from bootloader code to application code. Is there any demo code for such solution
