I had flashed "large" image to my RB411AH board and it works like a charm. Great work! I am sorry that I missed that this images differ only in the page size and I did not try this image before. Thank you for your support! BTW, in previous mail I forgot to specify that the flash chip model is TC58DVG02D5TA00. > To prevent flashing errors like the one you had, maybe it would be a > good first step to add metadata to the image and make sysupgrade set the > board type to nand-64m or nand-large depending on the flash parameters. Looks like boards with the same name could be equipped by different flash models. Could we just add new optional metadata field 'flash-page-size' to avoid growth of number of board types? And entitle images like 'mikrotik-nand-pg512', 'mirkotik-nand-pg2048'? -- Sergey _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
