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 Writingby gdm85 - Displays
