`load` works every second time #420

Closed nickray closed 2 years ago

nickray commented 5 years ago

Hi

I have converted one RobotDyn "Black Pill" to a BMP, and am flashing to a second same board. Everything works, but every other load fails:

(gdb) load
Error erasing flash with vFlashErase packet
(gdb) load
Loading section .vector_table, size 0x130 lma 0x8000000

Any ideas how I can debug this? I can workaround by just running the flashing twice, one of them will work :)

I'm using a simple gdb script:

target extended-remote /dev/ttyBmpGdb    
monitor swdp_scan    
attach 1    
load    
compare-sections    
kill    
quit

Compile with "make ENABLE_DEBUG=1 PROBEHOST=..." . Run the gdb command by hand. Before scan, enable DEBUG and open the second usbuart.

so I ran into this today after upgrading one of my probes to latest master, however when building as suggested above I get this:

platforms/stm32/usbuart.c: In function 'rdi_write':

hydra commented 5 years ago

the missing debug_bmp was easily fixed in the code for the platform i'm using (baite).

then I got another error about incorrect print formatting, I'll raise a PR for that. was able to compile.

hydra commented 5 years ago

Managed to capture a failure.

I used the load command 4 times here, on the 3rd time it failed.

Using latest master + tasitgast baite patch + debug compilation fixes and an H750 CPU.

UweBonnes commented 5 years ago

There is no baite platform in our master tree. What code base do you refer to?

hydra commented 5 years ago

The one from #274

@nickray was using a different one to me so not sure if it's probe specific.

esden commented 2 years ago

Is this still an issue? Any clues of what is going on? Maybe it is a marginal connection issue? This could also lead to intermittent programming issues.

hydra commented 2 years ago

@esden I've not seen this issue recently, and I've flashed a bunch of H750/H730 boards. The code I'm running on my BMP is built from commit f9414d58265093bf8a4ae59d45c3d1ac441d6ed2 from (master) which Baite support was also added into the STLINK probe_host.

Thank you very much @hydra. In that case I will close this issue for now. If the problem comes back feel free to open a new issue and we can work on figuring it out. :)
