bload on acme_7 AX206: Resource temporarily unavailable
December 31, 2016 06:47PM
I managed to flash multiple times an acme_7 AX206 DPF (it's a buildwin tiny 1.5" frame), however no luck at using bload to run firmwares from RAM.

I have also built sdcc 2.9, and then the necessary fw_acme_7.bin. I always get the same error:
sudo ./bload ../tools/fulldump_20161230-204312.bin 
Found AX206 DPF (bootloader)
Writing to USB: Resource temporarily unavailable
Writing to USB: Resource temporarily unavailable
Writing to USB: Resource temporarily unavailable
[...]

Any ideas where to look at? I tried both with usb_interrupt_write and usb_bulk_write in rawusb.c, same result. I have read this could be due to the cable, but even when flashing is fine? It seems more like a software/firmware problem to me.

Thanks
