USB IAP for Firmware Download

Hi,

I want to use IAP with USB and use remapping if necessary. Unfortunately I have got a problem with the assembler files (71x_init.s, 71x_vect.s, init_table.s) and the xlink command file. Are these files described anywhere? When I try to compile my sources, I get the following linker error:

Error[e18]: Range error, ARM branch target is out of range

Where $ = T0TIMI_Addr + 0xCC [0x400000CC]

in module ''?RESET'' (D:\Firmware\FW_L000100(WaMa)Download\Debug\Obj\71x_vect.r79),

offset 0xCC in segment part 0, segment INTVEC

What: Undefined_Handler - ($ + 8) [0xDFFFFFA4]

Allowed range: 0xFDFFFFFC - 0x2000000

Operand: Undefined_Handler [0x20000078]

in module 71x_it (D:\Firmware\FW_L000100(WaMa)Download\Debug\Obj\71x_it.r79),

Offset 0x0 in segment part 5, segment CODE

Any suggestions?

Thanks!

Bye

Hi,

thanks for your help! I have still a problem with irqs. When I start the FLASH_WordWrite and an irq happens, LR-Register is overwritten. When I run it in debug mode, it runs fine. As a work around I disable the irq during the flash write.

Do you have any idea, why the LR-Register is overwritten?

The new version is at:

Hi

I am about to start work on a simila project, i was wondering if you could give any examples or tips of things that you had problems with. Also did you use VCP drivers? what descriptors did you use for the USB.

Thanks

Hi Moe,

Did you resolve IAP with USB.

If you have, do you have sample code that I could use

for my project.

What gui did you use on PC side ?

Thanks,

Mik

We have released a new ''USB Developer Kit for STR7'' beta1 that supports all USB transfer types:

- Interrupt transfers with HID Mouse/Joystick Demo

- Bulk transfers with Mass storage Demo

- Isochronous transfers with Voice Speaker Demo

On top of this, it provides an implementation of DFU for Firmware update using USB.

Please find the zip file in the following link:
