Die Pinbelegung der Platine passt zu FlashFloppy (Gotek-Standard), das Display funktioniert am Arduino. Ursache war der Controller: Verbaut hatte ich einen STM32F105<strong>R8<\/strong>T6 mit nur 64 KB Flash. FlashFloppy braucht beim STM32F105 aber 128 KB (32 KB Bootloader, danach die Firmware und am Ende eine Seite f\u00fcr die Konfiguration). Das war mein eigener Fehler: Ich hatte mich vorher nicht informiert, wie viel Flash FlashFloppy braucht. Am Projekt liegt es nicht. Dessen St\u00fcckliste nennt nur \u201eSTM32F105R\u201c ohne Flash-Gr\u00f6\u00dfe, die Anforderung ergibt sich aus FlashFloppy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L\u00f6sung: Einen Controller mit mindestens 128 KB verwenden, also STM32F105RBT6 \/ RCT6 oder den pinkompatiblen Artery AT32F415RCT7 (bzw.

Neuerungen aus FlashFloppy passen nur, solange die rund 1,3 KB Reserve reichen.

Die Platine hat keinen Reset-Taster, also USB abziehen und wieder anstecken. Danach gingen alle Raten von 9600 bis 115200.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"flashen-ohne-boot0-keine-ausgabe\"><span class=\"ez-toc-section\" id=\"Flashen_Ohne_BOOT0_keine_Ausgabe\"><\/span>Flashen: Ohne BOOT0 keine Ausgabe<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ohne BOOT0 kommt auf dem seriellen Port nichts an. Das ist normal, denn FlashFloppy gibt dort nichts aus.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L\u00f6sung: BOOT0 muss schon beim Einschalten auf +3,3 V liegen, erst dann stm32flash starten.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"flashen-anzeige-flash-up-to-256kib\"><span class=\"ez-toc-section\" id=\"Flashen_Anzeige_%E2%80%9EFlash_Up_to_256KiB%E2%80%9C\"><\/span>Flashen: Anzeige \u201eFlash: Up to 256KiB\u201c<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">stm32flash zeigt beim STM32F105R8T6 \u201eUp to 256KiB\u201c an.

F\u00fcr die normale FlashFloppy reicht das nicht.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L\u00f6sung: Keine n\u00f6tig.

Erst nach erneutem Ab- und Anstecken erschien FlashFloppy. Vermutete Ursache: BOOT0 h\u00e4ngt ohne Pull-down in der Luft, der Controller startet dann zuf\u00e4llig im Bootloader (siehe \u201eBOOT0 ohne Pull-down\u201c).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L\u00f6sung: 10-k\u03a9-Widerstand zwischen BOOT0 und GND einl\u00f6ten.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"fehler-40h-am-8088-floppy-kabel-verdreht\"><span class=\"ez-toc-section\" id=\"Fehler_40h_am_8088_Floppy-Kabel_verdreht\"><\/span>Fehler 40h am 8088: Floppy-Kabel verdreht<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Am 8088 mit dem <span class=\"ub-content-link ub-content-link--ok ub-content-link--status-after\"><a href=\"https:\/\/www.fambach.net\/en\/retro_pojekt-retro-projekt-floppy-disk-controller-isa-fdc\/\" class=\"ub-content-link__anchor\">8-Bit-ISA-FDC von Kiselev<\/a><span class=\"ub-status ub-status--ok\" title=\"Link status: OK\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: OK<\/span><\/span><\/span> meldete das BIOS \u201eError 40h\u201c (Seek failed).
