Hi Alan, many thanks for your hints!! In my this situation, the -29 error is returned by ret = elf_load(&loadinfo); But, turned out that the error was coming from the NXFFS.. I reformatted the volume from which I was loading the ELF file, and the error disappeared, working well.. Takes some seconds to load the binary, but this is because the I2C EEPROM is running only at 400KHz max. Best regards, FLorian On 03/04/2020 11:36, Alan Carvalho de Assis wrote:
Hi Florian, The error -29 is -ESPIPE : Illegal seek. Probably it comes from here: if (offset > iob->io_pktlen) { ioberr("ERROR: offset is past the end of data: %u > %u\n", offset, iob->io_pktlen); return -ESPIPE; } Please try to enable CONFIG_IOB_DEBUG and see if the above error message is printed. Then you can track why it is failing.

My problem is the size of my elf file, it is up to 12K. This is basically because I've packed all the features into 1 task (network, file I/O, json, etc) because it would be more simple to update a single elf file rather than have a lot of different elf files for different tasks and having to maintain a "repository" of those tasks. My question is, is this somehow stupid to do? Is there a reason why I should avoid to load "bigger" elf-files? The system has enough RAM: nsh> free total used free largest Umem: 229072 17760 211312 211136 What happens is, when the elf file is bigger than about 4K, the binary loader encounters a problem, independently on the config settings of the elf buffer sizes: CONFIG_ELF_STACKSIZE=10240 CONFIG_ELF_BUFFERSIZE=256 CONFIG_ELF_BUFFERINCR=32 here's part of the debug output: elf_loadshdrs: Insufficient space in file for section header table elf_dumploadinfo: LOAD_INFO: elf_dumploadinfo: textalloc: 00000000 elf_dumploadinfo: dataalloc: 00000000 elf_dumploadinfo: textsize: 0 elf_dumploadinfo: datasize: 0 elf_dumploadinfo: filelen: 5360 elf_dumploadinfo: filfd: 3 elf_dumploadinfo: symtabidx: 0 elf_dumploadinfo: strtabidx: 0 elf_dumploadinfo: ELF Header: elf_dumploadinfo: e_ident: 7f 45 4c 46 elf_dumploadinfo: e_type: 0001 elf_dumploadinfo: e_machine: 0028 elf_dumploadinfo: e_version: 00000001 elf_dumploadinfo: e_entry: 00000555 elf_dumploadinfo: e_phoff: 0 elf_dumploadinfo: e_shoff: 5056 elf_dumploadinfo: e_flags: 05000000 elf_dumploadinfo: e_ehsize: 52 elf_dumploadinfo: e_phentsize: 0 elf_dumploadinfo: e_phnum: 0 elf_dumploadinfo: e_shentsize: 40 elf_dumploadinfo: e_shnum: 11 elf_dumploadinfo: e_shstrndx: 8 elf_loadbinary: Failed to load ELF program binary: -29 Thanks a lot for any help!!
