Proof step 5 from proof inv-write-echdr (previous step)

pebs[m0] = mkpeb(buf, 0, false), aehdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪ubi_io_write_echdr#(m0, aehdr, EB_PAGE_SIZE; pebs; err)⟫ mtd-cons(pebs)

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 6:
pebs[m0] = mkpeb(buf, 0, false), m = EB_PAGE_SIZE, aehdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪if m0 < # pebs ∧ aehdr.valid? ∧ ¬ pebs[m0].bad ∧ pebs[m0].fill = 0 then let buf = mkbuf(m), ehdr = echdr(aehdr.ec) in {encode_echeader#(m, ehdr; buf; err); if err = ESUCCESS then mtd_asm_write#(m0, 0, 0, m, buf; pebs; err)} else abort⟫ mtd-cons(pebs)
