stm32f103xb stuck at bootloader #988

Closed luckyxiaoer closed 1 year ago

luckyxiaoer commented 1 year ago

Hi, I tried to use Nucleo-L476RG board to port daplink using keil, but failed to get it work

I've tried servial things

drag-n-drop

I've generated stm32f103xb_bl and stm32f103xb_stm32l476rg_if project, after compiled them, I got bin and hex file .

I download stm32f103xb_bl to board using Jlink. and get a Maintenance disk in My computor.

after I drag-n- droped stm32f103xb_stm32l476rg_if_crc.bin

the Maintenance disk disappered , but shown again.

my detial file in Maintenance disk show below.

flash merge file

I use hexview to merge the bl.hex and if.hex but the program still stuck in bootloader

breakpoint debug

I debuged it in keil step by step , and find it failed to jump to app because of the 

validate_bin_nvic((uint8_t *)g_board_info.target_cfg->flash_regions[0].start

and it returns false because 

g_target_family && g_target_family->validate_bin_nvic

is always NULL

and I found no function to refresh g_target_family in bootloader .

no idea

by now , I have no idea to solve this problem , and looking for your help , thank you ~

It's normal g_target_family && g_target_family->validate_bin_nvic would be false, it should move to the default validation function validate_bin_nvic_base(). You can check that the interface image starts with interrupt vectors that look consistent.

I don't understand what you mean when you say you want to use NUCLEO-L476RG to port DAPLink using Keil.

Hi mathias: it turns out to be the fault of the hardware config of the jumper5 in my NUCLEO-L476RG; the Jump5 was lost before, so there was no power supply for stm32l476 and the NRST pin got no pull-up, and it stay in low voltage level, even the reset bottom had not been pushed , so the program stuck in bootloader.

after insert the jumper5， it shows a DAPLink disk in my computer . and I compiled a gpio program for stm32l476 from the stm32 official demo.

but it failed to be flashed into stm32l476 , and shows a ASSERT.txt

the ASSERT fault was caused by the wire connection for SWDIO 和 SWCLK between STM32L476 and STM32F103. program runs normally, after wires removed.
